The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a signed 17-jewel hand-winding movement, Cyma calibre R458, which is working nicely. There are a couple of empty retaining screw holes within the movement, the retaining screws are not required in this particular case as the movement is designed to be held in place by the shaped case back.

The watch measures 32mm diameter excluding the winding crown and the nicely shaped lugs. The case is chromium plated while the case back is stainless steel. There is some rubbing to the high points of the lugs but not too detrimental. Light surface marking but all very acceptable for a 1950s piece.

Despite the name Watersport, the watch should be kept away from water and moisture.
The lens is in lovely condition.
A later leather strap has been fitted.
The watch comes in a new presentation box.
