Atlantic

 By Bruce Shawkey

Found this ad in the Nov./Dec. 1958 issue of Swiss Horological Journal for an Atlatic "Travelmatic" Watch. It was an automatic watch with 25 jewels (you need only 17!) a sweep second hand, and date:

Ed. Kummer was established in Bettlach, Switzerland in 1888 by Eduard Kummer, born 26 March 1845.

Here's an ad for an Atlantic "Travelmatic" that appeared in the March/April 1958 issue of Swiss Horological Journal. Atlantic was a brand of Ed. Kummer SA of Bettlach Switzerland, in the Canton of Solothurn. The watch pictured is an automatic wind with date.
