And for reference my wrist is just about 6" in circumference so it is damn tiny, I am glad that it is at least more flat than round so I could usually accommodate up to 40mm round watches. When trying on the tanks, I couldn't tighten any of the straps up because they were simply too long.
I think it was suggested up-thread as well, but have you considered the Reverso Classique?
As someone also highly drawn to the design of the Tribute to 1931 models but finding them too large - especially for this type of watch - I think the Classique would be the best bet. Clean dial, nice proportions and a solid case back. At 38.5mm for a rectangular watch, I can't imagine wanting it to be larger.
Actually, looking at it now again, it seems like the perfect dress watch addition to my couple of round, black faced sports watches. Goddamnit.
