I purchased this awesome blue dial Type XX a few years ago. Unfortunately, it came with a serial number that was partially damaged – it looks like someone tried to open the watch with the wrong tool and scratched it. When I bought it, I didn't know any better ... and the watch worked fine for a whil

It’s really a great watch, but I just don’t get much opportunity to use it. It seems silly to just let it languish in a safe deposit box.
