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. The case is plated and there is general surface marking and wear commensurate with its age.
The back of the watch has the military arrow, or pheon and the GSTP lettering (General Service Time Piece).

The watch glass is in lovely condition.
The signed dial is in lovely condition. The paint has been removed from the hands and numbers 3, 6, 9 and 12 in the past, probably because of the radium content.
The watch comes in a new presentation box.
