The Vintage Wrist Watch Company has dated this piece to the 1940s.
The watch has a Swiss 15-jewel hand-winding movement, signed Cyma, which is working nicely. There are a couple of empty holes within the movement, these are for retaining screws.

The watch measures 32mm diameter excluding the winding crown and the lugs. The case is stainless steel and it is in very nice condition. The case back is signed with the Cyma name. Despite the Watersport name, the watch should be kept away from water and moisture.
The lens is in lovely condition.
The signed dial is in its original finish with original hands, a subsidiary seconds dial and outer minute markers. There is light marking across the dial.
A new leather strap has been fitted.
The watch comes in a new presentation box.
