This is a Zenith wristwatch manufactured in the 1950s, a rare “Saurer” double-signed stainless-steel model equipped with the Cal.126-6. It is an untouched piece with a two-tone dial.
This is a valuable double-signed model made for Saurer, the Swiss industrial manufacturer known for producing trucks, engines, and machinery. The two-tone dial, featuring a blue-and-gold Saurer emblem, exhibits a level of originality that sets it apart from standard double-signed models.
It is powered by the Cal.126-6, notable for its beautiful graining and chamfered finishing. When the caseback is opened, you’ll find an additional transparent inner cover—an unusual construction reminiscent of military watches from the 1930s.
Overall preservation is excellent, with the case retaining its original shape without any polishing or external refinishing, and with the original dial showing attractive, natural aging. This is a one-owner–type piece that conveys an authentic and untouched vintage character.
