Wrist Watches issued to Commandos

Hello,

I am a keen collector of military watches in particular WW2 British Military Watches and am researching the original of a particular wristwatch issued by the Hydrographic Survey to the Royal Navy circa 1953

The stores Code marked on the rear of the watch is H.S. 11

I was wondering if any members have any information regarding wrist watches that were issued to commando personnel between 1942 and 1960

regards

Mark Wilson
