The Vintage Wrist Watch Company has dated this piece to the 1940s.
Gents 1940s Valjoux chronograph wrist watch.
The watch has a 17-jewel Valjoux 22 hand-winding movement which is working nicely.
The Valjoux 22 was first introduced as a single button version in 1914.
The Valjoux 22 was used by several high end chronograph manufacturers including Heuer, Zeiss, Eterna and Vacheron Constantin.

The watch is a good wearable size at 36mm diameter excluding the winding crown and the lugs. The whole case would originally have been gold plated but most of the plate has worn off the case back and the lugs. There is minor marking to the case. The back of the watch has some marking and unevenness.

The lens is in lovely condition.
The dial is in its original finish. There is a small patch of scratching although not overly noticeable to the naked eye and also general marking / freckling across the dial. Two subsidiary dials, one for constant seconds and the other for recording up to 30 minutes. The top button starts and stops the chronograph and the bottom button re-sets to zero. The chronograph function should not be left to run permanently.
A new leather strap has been fitted.
The watch comes in a new presentation box.
