HISTORY
Atlantic history
https://www.atlantic-watches.ch/en/atlantic-history
The Atlantic company was established in Bettlach, a village near Grenchen Switzerland, in 1888. It was founded by Eduard Kummer, born March 26, 1845. He was one of the founders of Swiss watchmaking. During his many years of apprenticeship and further education in the Swiss Jura, he constantly refined his skills as a watchmaker. He came back to his native city as a qualified master of horology. The citizens of Bettlach recognized Kummer's business ambitions and supported the establishment of the industry, which soon became the heart of Swiss watchmaking. The vision of setting up a high-quality watchmaking business became true. In 1888, 15 to 20 employees worked in the first workshop. Over the subsequent years the factory developed steadily, reaching 720 employees before the end of the 19th century.
Although Eduard Kummer was known as very traditional, he believed strongly in the development of the watch industry. At that time, the workweek lasted 6 days and 11 hours per day. There was no such thing as paid vacation nor extra wages. The introduction, in 1937 of 6 days of paid vacation per year at EKB was a social breakthrough.
The company was originally called EKB (short for Eduard Kummer Bettlach). Initially the company manufactured parts for such renowned watch producers as Longines, Certina, and many others. The first watches under the name of “Atlantic” with a sextant as a logo were released in 1932, including one of the first waterproof chronographs. The invention of the “Speed Switch” in 1960 sets a milestone in the watchmaking history. The innovation allowed the date to switch 52 times faster than before. By selling this innovation to other watch manufactures, Atlantic clearly demonstrated its watch making skills.
Atlantic flagship models are from the “Worldmaster” family. With this piece, the company achieved a high degree of recognition and the models are still today regarded as the brand’s identification mark. The traditional “Worldmaster” is however constantly upgraded to stay timeless.
In the past, the Atlantic watches were aimed at strong personalities, who always pursued their goals and were represented in a high price range. Today, Atlantic has a wide range of watches, distinguished by their high quality, in a middle price segment. In addition to the timeless “Worldmaster”, Atlantic offers a wide selection of sporty, classic and elegant watches. However, what distinguishes the traditional models is their unique and specific Atlantic look.

RECOMMENDATIONS
All Antique watches are mechanical. Many repairs will not be cheap, as most likely they will require replacement of non-standard parts (unlike most late model watches).
- Antique watches should not be beaten or dropped - because repairs may be expensive.
- Antique watches are generally NOT waterproof. This is because waterproofing was not in general production until the middle of the 20th century for most watches. Therefore you should protect your antique watch from exposure to moisture.
- If your watch becomes wet it should be dried off quickly. Carefully open all covers and use a hair drier to blow dry the movement, dial, covers, crown. This will reduce the amount of rust.
- If your watch becomes wet with any kind of salt water you should immediately immerse or spray your watch with fresh (no-salt) water to remove all the salt from the works before drying the watch completely. Any salt left in the watch will combine with moisture in the air to rust metal components of the movement, case etc.
- Winding any mechanical watch tight may break the mainspring. If you can avoid it do not wind the watch hard.
- When adjusting the hands of your watch, move them in a clockwise direction only. Counter-clockwise adjustments may damage the movement. It is desirable to adjust the hands of your watch at the same time every day. An automatic or self-winding watch should be worn for at least 8 hours a day. It is a mechanical watch in which the mainspring is wound automatically as a result of natural motion of the wearer's arm, to provide energy to run the watch, making manual winding unnecessary.
- If you must adjust counter-clockwise make it for small adjustments only (i.e. for minutes, NOT hours).
- Be careful and gentle when adjusting the movement speed (faster or slower). Don't make sharp movements, and don't touch other components in the movement especially the pendulum mechanism.
- Every 2-3 years it is necessary to service and oil vintage watches. If the course of your watches is worsening and the accuracy of the reduction in the duration of the clock (autonomy) from one fully wound spring - it need a service.
- IF the watch is dirty - allow the watch to run down, don't wind it again until you have it serviced by a qualified watch repair expert. Dust will absorb and remove important lubricants and cause the movement pieces to wear down.
- To clean the case, dial and crystal you should use a cloth that does NOT leave fibers as these may get caught up in the movement. Check with your Watch repair expert to get an appropriate cloth.
- Keep your antiques watch away from magnets. Strong magnetic fields may affect the accuracy of your watch since some vintage watches were made with iron based components in the movement.
- Most Cases and Covers are fine components and will not handle abuse well. The watch should not be shaken, beaten, or stressed.
- Antique watches generally experience an error of up to 5-7 minutes a day. Any accuracy of +- 5 minutes is very good.
- Mechanical watch is not recommended to use for engage in extreme sports, and expose them to excessive vibration loads. Recoil force, which take on the clock, affect their reliability and precision. No matter how perfect was not anti-shock mechanism, there is always the chance of excessive load that details of the mechanism can not survive.
-
Watch with calendar. It is not recommended to adjust, the date between 20.00 and 06.00, because at this time involved a mechanism for automatic adjustment date. Translation pointers calendars manually in this position arrows may damage the mechanism. Date changes should be made, relegating pre-clockwise to lower sector of the dial (for example, to position 6 (18.00) hours).
-
Chronograph watches. In most cases, these watches contain the "start/stop" button and "reset" button. It is strongly recommended not to press the "reset" if the chronograph is running. Before you use the "Reset" button need to stop the chronograph by button "start/stop". Using the "reset" when running chronograph can damage the mechanism of most models of watches.
