The Vintage Wrist Watch Company has dated this piece to the 1930s.
Sales were so good that the Atlas factory struggled to meet the demand so movements were imported from other Swiss manufacturers such as IWC, Eterna and Patek Philippe.

This particular movement was made in the La Chaux-de-Fonds factory as it has the SS&Co beneath three triangles. This mark was used on Stauffer’s own highest quality movements, known as “third quality” (which, despite how it sounds, was their very best quality). The movement is working nicely and it is protected by an inner hinged cover.

The mark of SS&Co with the three triangles was registered in 1886 and this particular watch would date back to the early part of the 20th Century.
The watch measures 50mm diameter excluding the winding stem and the loop. The case is gold plated and is the Star model by the Dennison Watch Company, a prolific manufacturer of cases for various watch makers. The case is in good condition for its age, just some surface marking but nothing too serious.

The watch glass is in lovely condition.
The enamelled dial is in super condition with blued steel hands, a subsidiary seconds dial and an outer minute track. The dial is signed Week, Bradford, the original retailer of the watch.
The watch will be sent in a new presentation box.
