The Atlantic watch company was founded in Bettlach near Grenchen, Switzerland, in 1888 by Eduard Kummer. He was one of the founders of Swiss horology. The company was originally called EKB (Eduard Kummer Bettlach) and later, in 1930, renamed Atlantic. Eduard Kummer became a qualified master of horology and under his guidance the company grew quickly. Each Atlantic watch is equipped with a Swiss movement, and mid 1980’s the Atlantic Skipper was introduced, with a Valjoux 7757 regatta movement.

How the countdown function works:
The regatta caliber 7757 has the crown to set the time at 3 o’clock, and two pushers for the countdown function. One pusher at 2 o’clock for start/stop and one pusher at 4 o’clock for reset. Under the dial lays the indicator disk coloured blue, white and red. There are five round apertures cut out of the dial, between 10 and 2 o’clock.
After a reset the five dots colour blue. When the chrono is activated the countdown starts and the sweep hand is set in motion. The indicator disk runs continuously clockwise. After one minute the first dot colours red, and after five minutes all 5 dots colour red. Again one minute later, so after 6 minutes, the first dot colours white. And after 10 minutes all dots colour white. Unless you push the stop pusher, the indicator disk doesn’t stop revolving. After another 5 minutes it’s coloured blue again, and so on. So the regatta countdown function can be used for a 10 minute start as well as for a 15 minute start.

The Valjoux regatta caliber 7757 is a modified caliber 7750, with a 15 minutes countdown module integrated. According to Juerg Bohne of Atlantic Watches, the Swiss compagny Dubois-Dépraz was involved with making the regatta module. But the movement is listed as a Valjoux 7757 in their catalogue.

Other watch brands that used the caliber 7757:
Over the years some pictures popped-up with smaller brands using the regatta caliber 7757. Sofar I found three of them:
De left one says ETA Swiss Technology. Perhaps some sort of demo model by ETA? The second one is marked Luxor, and the last one Prospec.
