Hi All,

I recently bought my first Heuer -- an 1163V. It's in good shape, but was in need of a service. My watchmaker has it, and in disassembling it for service he noted that the set bridge was broken. He's working on seeing if he can source one, but he's far from a Heuer expert. Given the staggering expertise on this forum, I figured i'd ask:

1) is the set bridge between cals 11 and 12 the same (i believe it's part # 445)? I read Jeff Stein's description of the difference between the calibers, and this isn't mentioned.

2) separate from whether it's and 11 or 12, are the parts interchageable between Heuer, Breitling, Hamilton, Universal Geneve, etc?

3) Aside from the UG Cal 11 set bridge I found online, I see very little else. Is there a source anyone can recommend for sourcing a part like this? I imagine the supply for older chronos is drying up, and it will just get harder and harder to find parts.

Thanks so much!
