The Atlantic company was established in Bettlach near Grenchen, Switzerland, in 1888.
It was founded by Eduard Kummer, born March 26, 1845. He was one of the founders of Swiss horology.
The company was originally called EKB (short for Eduard Kummer Bettlach), and later renamed Atlantic. The company adopted an anchor and compass as its logo, and took its name from one of the oceans.
Initially the company manufactured parts for such renowned watch producers as Longines, Certina, and many others.
The first watches under the name of Atlantic were released in 1932, including one of the world’s first waterproof chronographs. Another very important event, which took place in the 1950s, was the invention of the crown-operated quick date-change mechanism.This landmark invention, compared to the invention of the crown in watches by Patek Philippe, is still used today by all watch manufacturers in the world.
During its 125 years of production, the company introduced many innovations, such as the titanium Nautilus, waterproof up to 1000 meters, or the Midas – a watch with an extra durable case and resistant to scratching.
However, the most famous model (and then series) of the Atlantic brand, which gained the most consumer popularity, was the Worldmaster.
Most Atlantic watch self-winding movements can be wound properly by most watch winders. Usually Atlantic's self-winding movements need to rotate 650 to 1000 revolutions per day, and most of them can be wound clockwise. So please take some time and like to choose a cute clockwork that suits you and your watch.

If you could not find your watch model (or caliber) in this table, you may determine your Atlantic winding mode on a trial basis. You should select the combined winding mode (CW+CCW) and the minimal number of turns per day (TPD). Then place your watch into the watch winder and check after a few days how accurate your watch shows the time. If it runs behind, it is necessary to increase the number of TPD by one step.
