The Vintage Wrist Watch Company has dated this piece to the 1940s.
The movement is signed Smiths.

The watch measures 29.5mm diameter excluding the winding crown and the lugs. The fashion was for men to wear smaller watches in the 1940s and 1950s so this watch is on the small side and it would suit a gent with a slimmer wrist, or it could be worn by a lady. The Denisteel case by Dennison has some marks, mainly to the bezel, and some unevenness to the case back.

The lens is in good order.
The dial is in its original finish; there is light marking but it is very acceptable, especially for a 1940s piece.
A new black leather strap has been fitted.
PRICE INCLUDES WORLDWIDE POSTAGE
