Sandoz

 By Bruce Shawkey

It seems everybody was making dive watches in the mid to late 1950s. That's because equipment manufactures came up with the Aqualung and other devices that allowed divers to go deeper than ever before. These improvements  were due in no small part to Jacques Cousteau, the famous French naturalist. One of the many companies to come out with dive watches was Sandoz. Here are a couple of example from an ad in Europa Star magazine:

Sandoz is a Swiss watch brand, originally established in the late 19th century by Henri Sandoz near Tavannes, Switzerland. There are many variations of the Sandoz name which are used by at least four different companies around the world.

Here are some images of Sandoz watches through the decades:

Here are addition articles on Sandoz watches I have written:

Found this ad in the March/April 1960 issue of Swiss Horological Journal for a Sandoz Model 333 self-winding watch. The movement had six ball bearings, an obvious effort to compete with Eternamatic's five ball bearing watches:

The ad even stated that 1,000 of the ball bearings would fit into a thimble, the same statement made by Eternamatic.
