The Vintage Wrist Watch Company has dated this piece to the 1920s.
Sales were so good that the Atlas factory struggled to meet the demand so movements were imported from other Swiss manufacturers such as IWC 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 itself measures 52.2mm diameter excluding the winding stem and the loop. The case is silver and has Birmingham hallmarks for 1925 with the makers mark for the Dennison Watch Case Company. It is in good condition with just light surface marks from use and a small "ding" to the back.

The watch glass has minor marking from use although it is in nice condition for a 1920s piece.
The white enamel dial is in nice condition with blued steel hands, a subsidiary seconds dial and an outer minute track.
The watch will be sent in a new presentation box.
Price includes worldwide postage.
