Zodiac Aerospace GMT Help

Started by sodorisio, February 11, 2020, 05:44:11 PM


I recently reserved a Zodiac Aerospace GMT on eBAY, however, upon further review it appears the movement has a cal 70-72, and not the standard 75. I have found a few instances of this occurring through my research, but not enough to feel confident that it was legitimately used by Zodiac in the 1960's. Not sure if this is allowed, but here is the listing:

Everything else appears correct, dial, hands, bezel, etc. Need some expert help here.

Thanks everyone!


i believe a cal 75 or 75B were in the GMT's...


According to lot pictures, it could be just later rotor replacement. Everything else look original.
