The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a seven jewel stem-winding movement, grade 292, which is working nicely. The movement is fully signed and the serial number 18275475 dates it back to 1915. The movement is protected by an inner hinged cover. This inner cover has some marking where it has been opened in the past.

The watch measures 50mm diameter excluding the winding stem and the loop. The case is gold filled and is the J Boss model made by the Keystone Watch Case Company. The nicely engraved case has a vacant cartouche to the front. The case has light surface marking from use but overall it is in nice condition for a 1915 piece.

The winding crown pushes in to open the front cover. Inside there is a glass lens which is in good condition.
The watch comes in a new presentation box.
