I recently posted on this 2791 cal 266 black dial arrival. Well I had an opportunity to get a sweep seconds 2640, cal 283, counter part to that watch and could not resist it. These large, 36mm manual wind-up are now classics and very collectable. I'll be on the lookout for interesting variants.
That must have been a very flamboyant looking lizard who's know wrapped around your wrist, really sets off the dial on that watch, looks cool!
