Wow, that's an early one with the non-reinforced hands and the different back with the 10 ATM rating. The case looks great and even the dial. I'd leave the dial alone. The lume is faded, but I think it adds character and the originality is worth preserving. Finding one of those skinny, early bezels might prove difficult, but that's part of the fun. Do you have one available?
What are the plans?
