First a comment about the 1570/1575 calipre, followed by a question or two about the other GMT movements.

I also have a 1970 (based on serial #) Rolex GMT with a 1570 Calipre. When I bought the watch in about 1982 it was pretty well trashed. The previous owner was a welder and there was weld spatter everywhere, including on the SS case. I had the watch rebuilt and installed a new band and it has been a good friend ever since. Regarding the movement, I feel confident that the 1570 was original, I'm sure that the first owner never took the watch in for anything. The first owner was English, I wonder if this might have something to do with the different numbers. Also, I'm wondering if a more accurate way to label the movements might be something like 1570 with 5 stacks of wafers (a apologize for not knowing the tech terms)? I'm not a watchmaker, but when they disassemble my watch, I'm always fascinated to see the beautiful stack of wafers as the watch is being disassembled.

One question I have about the 1675 - 1570/1575 calipre (1575 movement for the most part). Is this movement less robust than the 3075, 3085, 3175 or 3185? I'm thinking of moving up and giving my old friend a rest in a jewelry box.
