The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a 15-jewel grade 312 movement which is working nicely.
This calibre of movement was first introduced in 1906 but the serial number, 17183163, tells us that this particular piece was manufactured in 1913. The movement is protected by an inner hinged cover.

The watch measures 51mm 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 case is in good condition, just general light surface marks. The front and back of the case have engine turned detail with a vacant cartouche to the front cover.
The winding crown pushes in to open the front cover.
Inside, there is an acrylic lens which is in good condition.
The signed dial is in nice condition.
The watch comes in a new presentation box.
