The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a Swiss stem-winding movement, signed Columbus, which is working nicely. The movement also carries the mark for Schild Fréres & Co who went on to become Eterna. The movement is protected by an inner hinged cover.
The watch measures 50mm diameter excluding the winding stem and the loop. The case is 800 silver and there are Continental hallmarks inside all three covers.
Originally there would have been a rose gold wash around the edges but most of this has rubbed off. The front of the case has a central cartouche with the initials OW or WO. There is some gentle unevenness in places, mainly around the sides of the watch. Overall, the condition is very acceptable.

The winding crown pushes in to release the front cover.
The glass lens is in lovely condition.
The dial has a couple of faint hairlines but not overly noticeable to the naked eye. The hands are lever set (the lever is next to number 5).
The watch comes in a new presentation box.
