Thanks. I agree MWR is the right place, I’m on there as KJH666. Doing exactly as you say got me my Australian Smiths DeLuxe GS watch which had been restored by Crispin Jones (mrjones) with help from John Senior. Crispin kindly responded to aWTB and agreed to sell the watch, which I wouldn’t have stood a chance in hell of finding anywhere else.
Gratuitous wrist shot and a very similar case shape to the Longines.
