Hi everyone.
Looking for a balance complete (part 721) for UT376, which seems to be compatible with UT176.
Looking at CousinsUK (screenshots below) and the Part 721 is not available, but Part 721.1 is.
Any insights on the difference between part 721 and 721.1? I can see on the description that the 721.1 is shockproof but not sure if the part will be compatible. This is for a ~1950 watch with no incabloc.
Many thanks,
Claudio
