The Vintage Wrist Watch Company has dated this piece to the 1940s.
The watch has a 15-jewel stem-winding movement, signed Cyma, which is working nicely.
The watch measures 52mm diameter excluding the winding stem and the loop.
There is also some unevenness to the back of the watch. The back of the watch has the military arrow, or pheon and the GSTP lettering (General Service Time Piece).

The glass lens has light marking but is very acceptable.
The signed dial is in good condition. Originally the dial would have had radium paint on the numbers but this has been removed over the years.
The watch comes on a vintage leather albert.
The watch comes in a new presentation box.
