PINTEREST EXPLAINED

Pinterest is a bulletin board type of social link and image sharing service. It provides the opportunity to create and maintain collections based on a theme such as an event or a hobby. The user can also browse other link / image collections, extract parts from their own collections and report their liking for the link / image.

People use Pinterest to discover and save ideas. Ideas can take lots of forms, from recipes to renovation projects to the perfect pair of shoes. Every idea is represented by a “Pin” that includes an image, a description and a link back to the image’s source online. When people click a Pin’s URL they can find out more about the idea and act on it.

Pinterest user has increased rapidly in last few years. Pinterest announced in October 2016 that its monthly number of users exceeded 150 million. In one year, it had grown by 50 percent, as in September 2015, the company announced that it had 100 million active users. The number of users in Pinterest has grown rapidly, and in 2012 it was considered the fastest growing community service in the world. In August 2012 Pinterest had 23.5 million monthly U.S. users.

Pinterest has fewer users worldwide than Facebook or Twitter. In the US, however, it overcame Twitter in 2016. In October, Pinterest had 70 million users in the United States when Twitter had 60 million in June.

To remove scratches from your watch is pretty easy task. You do not have to be a watchmaker or you do not need any special tools for scratch removal of your acrylic watch crystal. You just need 5-10 minutes of your time, a little bit focusing and tender loving care to polishing crystal.

So what do you need then to accomplish polishing task? All necessary “tools” are shown in main picture. You just need to purchase Polywatch, cleaning and/or polishing cloth and the watch of course. We used different cloth to rubbing Polywatch to crystal and wiping off.

Here is the scratch removal procedure explained and illustrated step by step:

1. Check where scratches are located. We had bigger scratched in the middle Of Nivada watch crystal and slight scratches around crystal.

Before polishing
Slight scratches on crystal

2. Apply Polywatch to the watch crystal. 

Add Polywatch to the crystal

3. Use a piece of cotton wool and polish the scratched areas for 2-3 minutes with great pressure at a right angle to the scratches. Deep scratches need to be treated more than once.

Rubbing Polywatch to the crystal

4.Finally, remove any remaining Polywatch with a cloth.

After polishing

How Polywatch works:

  • The plastic glass is very slightly dissolved and ground down by tiny abrasive particles
  • The edges of the scratch marks are then smoothed off
  • The cracks filled in with some of the original plastic from the watch crystal

Now it is your time to try watch crystal polishing! This is easy way to get your acrylic crystal to the original condition. After polishing crystal looks like new. Note that Polywatch is working only for acrylic (plastic) crystals. It is not working for mineral and sapphire crystals!

You can find Polywatch from our online store.

Check review video on Youtube about Polywatch:


You might heard commonly used terminology like ”Swiss Made”, ”Swiss Movement” and ”Swiss Parts”. You can see often ”Swiss Made” and sometimes  ”Swiss Movement” in your watch dial. These terms can be a little bit confusing and you might have been thinking proper meaning of those. Timemachine.fi explains background of these terms so after reading this post, you will be even more clever!

There has been new regulation put into place in on 1.1.2017 what qualifies ”Swiss Made” watch. New regulation is more strict than before and it is regulated by Federation of the Swiss Watch Industry (FH). Regulation aim is to improve protection of ”Swiss Made” label and watch manufacturing in Switzerland. This way low-cost watch brands have harder to get ”Swiss Made” label into watch dial. Previous regulations are downloadable from Federation of the Swiss Watch Industry homepage: http://www.fhs.swiss/eng/swissmade.html

Explanation of Swiss Made, Swiss Movement and Swiss Parts by NEW regulation:

Swiss Made Watches:

  • its movement is Swiss
  • its movement has been cased up in Switzerland 
  • final inspection by the manufacturer took place in Switzerland
  • at least 60% of the manufacturing costs is generated in Switzerland 
Bulova automatic watch

Swiss Movement

  • have been assembled in Switzerland 
  • have been inspected by the manufacturer in Switzerland
  • at least 60% of the manufacturing costs must be generated in Switzerland
  • at least 50% of the value of all the constituent parts, but excluding the cost of assembly, must be of Swiss manufacture
Swiss movement pocket watch

“Swiss Parts” Movement

A watch is a “Swiss Parts” if the movement is not assembled in Switzerland, but still consist Swiss made components. Normally these types of watches are assembled in Asia or USA. There is no example of “Swiss Parts” seeing in dial. There is no marking on the watch dial like those of “Swiss Made” and “Swiss Movement” watches. Generally when buying a watch made with “Swiss Parts” you will only see this detail in the watch description. 

Swiss watch parts


HISTORY OF POLJOT

Poljot is a brand of Soviet/Russian wristwatches. Poljot watches has been produced since 1964 by the First Moscow Watch Factory. Poljot is the most famous brand of the USSR watch industry. 

Founded in 1930 under orders from Joseph Stalin, the First State Watch Factory was the first large scale Soviet watch and mechanical movement manufacturer. Via its USA-based trading company Amtorg, the Soviet government bought the defunct Ansonia Clock Company of Brooklyn, New York in 1929, and the Dueber-Hampden Watch Company of Canton, Ohio. It moved twenty-eight freight cars full of machinery and parts from the USA to Moscow in order to establish the factory. Twenty-one former Dueber-Hampden watchmakers, engravers and various other technicians helped to train the Russian workers in the art of watchmaking as part of the Soviet’s first five-year plan. The movements of very-early products were still stamped “Dueber-Hampden, Canton, Ohio, USA” (examples of these watches are very collectible today). In 1935 the factory was named after the murdered Soviet official Sergei Kirov.

As the Germans closed in on Moscow in 1941, the factory was hurriedly evacuated to Zlatoust. 1943 the Germans were in retreat, and the factory moved back to Moscow, adopting the “First Moscow Watch Factory” name (Russian: Первый Московский Часовой Завод – 1МЧЗ).

In 1947 the first wrist watches under the brand name “Pobeda” and the first Marine Chronometers and Deck watches were produced. By 1951 the production of wrist watches had increased to 1.1 million. In 1975 new machinery and equipment for manufacturing complex watches was imported from Switzerland. The first chronograph “Okean” (caliber 3133) was produced for the space station “Sojuz-23.”

In 1990 production of watches and clocks reached 5 million pieces, and in 1991 the international award “Golden Trophy for Quality” was awarded in Madrid.

Poljot has produced numerous historical watches used in many important space missions, including the world’s first space watch worn by Yuri Gagarin. Poljot literally means “Flight”. (Russian: Полёт) First Moscow Watch Factory has produced several different types of calibers such as 2409, 2415, 2609, but the most famous is reliable workhorse chronograph 3133 movement.

Poljot 3133 chronograph movement

POLJOT 3133

The Poljot 3133 is a manual winding chronograph movement produced since the 1980’s.

Introduced in the 1970’s but not generally available until 1983, Calibre 3133 includes elements of earlier Venus movements, notably the Venus 150, Venus 188, and Valjoux 7734. It is not a copy or clone of these movements, but Poljot did purchase machinery and tooling and adapt elements of these calibres into the evolving 3133 design.

The Venus company produced the cal. 188 from 1949 up until they withdrew from the marketplace in 1966. Another Swiss company, Valjoux, bought the tools and rights to produce the Venus 188 and continued to produce a slightly modified version of the chronograph, rebranded cal. 7730, through 1968. At this point, Valjoux further refined the movement as 7733, and 7734 with date function. The early production Valjoux 7734 most resembles what we know the initial production of the Poljot 3133 to be.

The Poljot 3133 is a cam controlled chronograph operating at 21,600 A/h. It has a 30 minute counter at 3:00, a small seconds dial at 9:00, and a central sweep seconds counter along with the hour and minute hands. A date window is located at 6:00. Two buttons control the chronograph functions: The 2:00 pusher for starting and stopping the chronograph, and the 4:00 pusher to reset the seconds and minute counters. Poljot 3133 is nominally a 23 jewel movement, but several jewels are used on both sides..

Some of the initial modifications made by Poljot to the 7734 included a taller main plate, third wheel plate with jewel bearing, jewelled chronograph gears, smaller and faster running balance with shock protection, and quickset date mechanism. Curiously, the initial version of the Poljot 3133 utilized the older version of the 7733/34 reset function (hammer, fly-back lever) that was produced between 1968-1971.

This is quite different from the Venus and Valjoux calibres with which it shares components and design elements. Those are slow 18,000 A/h movements with fewer 17 jewels. The Swiss movements use an entirely different assortment (balance and escapement) and has many differences in the bridges and levers. But many others are identical between the movements. The movements are not interchangeable either, since the dial feet are located differently, and the movement is 1 mm thicker. Interestingly, the date wheel on the Poljot advances clockwise like modern ETA movements, while older Venus calbres used counter-clockwise date wheels.

There are a few variants on the basic Poljot design. Calibres 31679 (with moon phase hand) and 31682 (with day/night display) include extra complications. The 17 jewel calibre 3105 lacks the chronograph functions and simply has sub seconds at 9:00 and date window at 3:00.

In 1974, a year after production began on the new cal. 7750 automatic chronograph, Valjoux discontinued production of the 7734 and sold the tools, and presumably the rights to produce the chronograph to Poljot. The ETA 7750 is still in production to this day , while the production of the MakTime 3133 ended in 2011.

Mechanically not too many modifications have been made to the Poljot 3133 over the last thirty plus years. Notable changes where an improved mainspring in 1987, an improved metal alloy balance wheel in 1992 and seemingly lower-quality levers and eccentrics from the late 1990s on.

Poljot continued to produce the 3133 chronograph up until the end of 2004, when the MakTime company purchased the Poljot 3133 machinery, relocated the equipment to their factory in south-east Moscow, and continued production starting in June 2005. After only a few short years, low-sales/profits and out-dated equipment forced an end to production in 2011. The MakTime company produced the cal. 3133 for a handful of companies including Moscow Classic, Volmax (Aviator, Sturmanskie, Buran), Juri Levenberg (Pilot, Strela), Poljot-International, PoinTec (Junkers, Zepplin), Poljot-Chonos (The President), as well as their own in house brands (MakTime, MWG).

As of July 2013, new movements continue to be available in remaining retail stocks, however, some of the more popular cal. 3133 chronographs, such as the Zeppelin models, are now nearing extinction.


Here is the brand story of FlyBuckle:

“Flybuckle is an aviation-inspired fashion accessory that encourages self-expression. We strive to minimize the impact on our environment by repurposing and upcycling industrial excess. Each Flybuckle is made of the same material used to produce commercial airplane seat belts. Every detail is authentic from the lift up metal buckle to the nylon webbing and high gauge thread used to create a sustainable experience. Because your belt should never put you on stand-by.

FlyBuckles have been available since 2013, and began when we realized that we shouldn’t have to discard parts and create more byproducts from the manufacturing process. We decided to create something fashionable that showed off our desire to make a positive impact and express our passion for reducing waste.” says company behind FlyBuckle.

FlyBuckle airplane belts are available in 5 amazing colours in Timemachine.fi. FlyBuckle belts has robust buckle and very strong nylon belt to minimize wearing in use.

This time we are showing and introducing the working principle of automatic belt. Automatic belt is very easy and handy to use because of ratchet mechanism. Ratchet mechanism enables to tighten belt easily and belt will be safely secured to your size. Opening of belt is also very easy to do, thanks to quick release lock.

Working principle of automatic belt is shown in following photos. Working principle is easy to understand, but we will still explain it here. The main features of automatic belt is its tooth rack and pawl mechanism. Tooth rack is located in inner side of belt. Pawl mechanism is located in buckle. Pawl is spring operated and its task is lock pawl to tooth rack so belt will not open by itself. Pawl mechanism can be seen in second photo. Pawl mechanism is installed by pin to buckle frame. Third photo shows how pawl is locked to tooth. Pawl is marked by red circle. Tooth shape enables that you can tight belt by pushing belt (tighten direction) through buckle , but pawl will not allow belt open without open locking mechanism. Locking mechanism can be easily open by turning locking lever show in fourth photo. Lever is marked by blue circle.

That´s it. Now you know how automatic belt works! 

Here is quick explanation how you can easily shorten your automatic belt for your size. It would be best when you are using belt that buckle would go approximately in the middle of tooth rack when measuring your waist. First put belt to your waist and check correct cutting place of belt. After this you can remove belt part from buckle by opening lever shown in fifth photo. Then cut belt from measured place and install belt back to buckle.

This time we are introducing five the most common vintage watch brands in Finland. There is not much information about Finnish watch brand in English. These brands are mainly sold in 60-70´s in Finland and in some cases in Sweden also. We are introducing five the most common vintage watch brand in this article. These brands are Leijona, Cardinal, Milljonär, Leopard and Tiger.

Watches in this post are from my private collection. Photo quality is not the best because these photos has taken a long time ago, before posting. Copyrights remains to the owner. 

Leijona:

Definitely number one of Finnish watch brand is Leijona. Leijona has established in 1907 and trademark is still working. Leijona is the most known, most popular and most used Finnish watch brand. Leijona watches has always designed in Finland. Leijona watches has designed for everyday use and you can wear watches in every situation.

Small story of Leijona´s history. The J.W. Lindroos watch wholesaler in Tampere (Finland), started to sell Leijona watches in 1910. 1918 brothers Jalo, Urho ja Oiva Perkko established Perkko Corporation in Helsinki. Perkko bought J.W. Lindroos company in 1919. In the beginning of Leijona history watches were manufactured in Switzerland and most of the watches were pocket watches. In 1920´s it started to come more and more wristwatches to markets for men and women. Even before 2nd world war they were wide range of mechanical wristwatches, pocketwatches and wall clocks. After war there became more selection with waterproof watches and other stainless steel and silver watches.

1970´s quartz watches replace mechanical watches in markets. In this stage Leijona quartz watches was manufactured in Japan. Nowdays Leijona watch collection consist of about 350 different types of wrist- and pocketwatches for men, women and children. There has been high level quality control since beginning and all watches has to fulfill hard requirements conserning of materials and production.

Cardinal: Cardinal was the brand of Kellotuomi co. ,the Finnish wholesaler, which built Cardinal on the example of Leijona brand. Cardinal came to the market on a trajectory, in the late 60´s when the production of cheap watches came to the transit stage. That is why there are much less Cardinal watches in the world if compared to Leijona. Mechanical watches did not sell in the 70´s, then at the end of the decade came the transition to quartz watches, first to the Swiss ones and early 80´s to Japanese Miyota movements. When Kellotuomi co. stopped operating -92, Exact Oy continued as a trademark holder. In the 80´s Cardinal had about 15% share of watch markets in Finland. Few years Cardinal was most sold watch in Finland.

Cardinal watches

Milljonär:

Milljonär watches were sold in postal sales between 1950s and 1970s. Probably watches were sold also in some retail stores. Tähti-Tuonti co in Helsinki started mail order business in 1958 and in the end of 60´s company started to advertise Milljonär watches in different magazines. Also the company called Swiss-kellot sold Milljonär watches in 1977 through mail order sales. According to the advertisements, the watches had AS, FHF, ETA and UT movements. Milljonär brand is probably a Finnish / Swedish marketing name, which is likely to be marketed only in the Nordic countries.

Milljonär Scandinavic

Leopard:

The brand was Sylvester Korhonen co. own brand in Finland. It was the largest players in the watch industry in Finland at the end of the 60´s. The brand may have been born in the early 50’s. Sylvester Korhonen’s wholesale went bankruptcy in the 70’s because of the quartz crisis, partly also by generation change problems. Sylvester continued its operations as a watch shop in Espoo, after a generation change.

Leopard watches have been assembled with the brand name in watchmaking companies in Switzerland. The operating model was very similar to Leijona brand. The Leopard brand went down with the Sylvester Korhonen wholesale company.

Tiger:

Tiger was a trademark of Aseman Kello co located in Helsinki. Tiger followed Leijona brand footsteps. According to the available information, watches were mainly manufactured by the Swiss watchmaker Mildia SA. The oldest Tiger watches from 60´s had FHF and ST handwinding movements or AS and ETA automatic movements. Tiger is much less sold than the other mentioned watch brands in Finland because it was sold only at watch shops of Asema Kello in Helsinki and Tampere and also in watch shop chain of Velikulta.

Mechanical watches and clocks have amazed people for centuries and now it is possibility almost every on build one. Timemachine.fi is now introducing very intresting project for watchmakers, watch hobbyists, engineers or people who just like to have fun with 3D-printer. 

Timemachine.fi introduces this amazing 3D-printed tourbillon which is fully functional. Creator of this masterpiece is Swiss engineer Christoph Laimer. Christoph is not a watchmaker. He has studied electrical engineering and working for 18 years for example in computer science inqustry.

“The Laimer Tourbillon is an innovative design with the heart beating highly visible in the core. The key function to indicate the time is direct and straight. Balance, escape wheel, tourbillon cage, hands, and barrel are all arranged co-axial. Gears for the transmission from the barrel, and the reduction from seconds to minutes and hours are placed behind the tourbillon in order to keep the design circular.

All parts are 3d-printed except a few screws and pins. The concept also includes a 3d-printed mainspring even though it is irrational (plastic is not elastic – it slowly flows and deforms). In order to make it 3d-printable, a lot of engineering effort was invested. The complete movement was essentially re-invented. The resulting timepiece works surprisingly well – of course, with it’s runtime and accuracy, it can’t compete with a conventional watch.The entire 3d-model is published and downloadable on Thingiverse. Many thanks to Nicholas Manousos for his great article in Hodinkee explaining the importance of my project from a traditional watchmakers perspective. Seeing his 3d-printed Tourbillon 1000% in action was very motivating to finish my work.” says homepage of Christoph Laimer.

The best part of this project really is that all 3D-models are downloadable in Thingiverse so all other persons can try to print and assemble very own 3D-tourbillon: 

https://www.thingiverse.com/thing:1249221

Check more details from this unique project from the inventor´s homepage where is also other intresting 3D-projects: http://www.laimer.ch/  and also Hodinkee website: https://www.hodinkee.com/articles/a-major-step-forward-in-horological-additive-manufacturing-christoph-laimers-3d-printed-tourbillon

There is another amazing 3D-project finished and project is 3D-printed triple-axis tourbillon by Adam Wrigley. Triple-axis tourbillon are probably one of the complicated subassembly to manufacture in watchmaking, because it needs hundreds of hours hand- and finishing work. Only few watchmaking companies are able to manufacture one. This one is also fully working and it has designed mechanical engineer Adam Wrigley at Frog design. Man himself is a mechinal watch fanatic. The final design consists of 99 parts: 34 printed parts, eight ball bearings, three metal shafts, two barbell plates, one meter of fishing line, and 51 screws. Read more about project from http://wornandwound.com/clockwerk-3d-printed-triple-axis-tourbillon-adam-wrigley/

If you are intrested to make your own, download all 3D-files of triple-axis tourbillon from Thingiverse: https://www.thingiverse.com/thing:1624844

If you have 3D-printer and you are willing to print your own tourbillon, you must have patient and time to print all parts. It can take up to 2-3 hours to print one part. Timemachine.fi encourage everyone to build own tourbillon! Go for it! Have a nice 3D-printing!

When you want to replace new strap for your watch, the first thing to do is to purchase proper spring bar tool. There is a lot of different types and quality levels in watch tools. Cheapest and poorest ones are commonly made in China. It is commonly known that Swiss made high quality tools are more expensive, but they will last longer and working process is much easier with well-made tools. If you are just beginner watch hobbiest, you can start working with chinese tools if you keep mind that they will break easily and it will take more time and effort to do anything with those kind of tools. 

Overall picture of materials

Changing strap for your watch is pretty easy job. Strap change can be completed in less than 10 minutes for a beginner and 2-3 minutes for someone with more experience. Choose your work area carefully so there is enough space for watch and protect glass side for example with towel. You should work from the back side of your watch. This ensure that if your tool accidentally slips, it will not scratch visible side of your precious watch.

In this post we will use famous swiss made manufacturer Bergeon´s watch tools. 

Poljot 3133 and Bergeon 6767-S

Changing strap process:

  1. From the back side of your watch, insert the forked end of Bergeon spring bar tool in between the strap and the watch lug. The spring bar has a ridge that the tool will grab, allowing it to compress.
  2. Gently apply pressure inwards and towards the strap (away from the watch) to depress the spring bar. At the same time, apply some downward pressure so the bar will popout. If you press to hard/fast, the tool may slip and damage your strap or scratch your watch. 
  3. Repeat on the other side, and you are all done! Remove the spring bars from the old strap. It is recommended to replace old spring bars with new ones.

There are different types of spring bars available. The differences can be found in end styles of bar and thicknesses. Most common types are double flange and single flange. Old watches might have some other types also. Normally spring bar diameter is 1,5mm, but if watch is heavy, it is recommended to use diameter of 1,8mm. Thicker spring bar is more durable and longlasting.

Old and new spring bar

Adjusting metal strap length:

  1. When you need to adjust the length of your metal watch band by removing links, you should first measure diameter of your wrist to ensure how many links you need to remove. Once you know how many links you need to remove, you need to decide how many links you are removing from each side of the band. Remember that anytime you are removing more than one link, you should split the total to be removed between both sides of the clasp so you can keep it center of your wrist.
  2. Next you will have to check and be sure which side of the watch band you want to start removing links. When you have decided where you want to remove link, examine the back of the watch strap. You should see several small arrows that show which way the pins need to be pushed out of the band. Sometimes there are not arrows showing push direction as here our bracelet in following pictures.
  3. Now, when you know which link(s) has to be removed, use your bracelet pin remover tool to push pin away located in link you are removing. Every link is attached with two pins, which have to removed when shorten bracelet. We are using in this post swiss made Bergeon 7230 tool, which can be found in our webstore. 
  4. Now when you have removed whole link from metal strap and strap is now seperated for two parts, you need to install strap (joint) back together with pin by reverse method. Now you have removed link and assembled strap back to one piece and strap is shortened. Well done!

See step by step instruction from the photos below the see how work is done. If you liked the tools shown in this post, you can find them and many more items in our webstore: www.timemachine.fi
