The Vintage Wrist Watch Company has dated this piece to the 1940s.
The watch measures 33mm diameter excluding the winding crown and the lugs. The case has general light surface marks but overall the condition is good for an early watch. The screw-on case back is stainless steel it states that the watch is waterproof but, as with most vintage watches, it should not be treated as such.

The lens is in good condition.
The dial is stamped Waterproof, Incabloc (which relates to the shock proofing), AntiMagnetic, Swiss Made. There are small marks to the dial but overall it has a charming vintage look. The hands have some discolouration and some of the infill has come out of the minute hand.
A new black leather strap has been fitted.
