The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a signed stem-winding movement which is working nicely. The movement is protected by an inner cover which has a little marking.
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 signature on the movement 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 overall is in good condition, again just the odd minor mark but nothing serious. The hinged case back has beautifully engraved initials of probably the original owner.

The watch glass is in good condition.
The dial looks good to the naked eye. If viewed through a magnifying loupe, there is a faint hairline running from the centre towards number 1.
The watch comes in a new presentation box.
