Wittnauer Wrist Serial Numbers

As such, many vintage Wittnauer watches have serial numbers that are listed under the Longines Company. Turn the watch over to determine if. In the 1950's Longines purchased the Wittnauer watch company and marketed a number of very similar lines of watches in the US under both brand names. In this authors opinion, Longines Wittnauer is one of the finest watches a collector can find.
