That vintage Zenith is beautiful. The Rainbow is nice as well but the old one is something else. Is the chrono second hand original to this model?
Thanks, the chrono seems to have come from a386 and not original to this a277, this model has 2 variants, one of which has white paddle hand (similar to what it has now but in white) the other variant (which actually is what the above watch should be) has a generic looking silver hand. You can see many great examples in the a277 thread found in this zenith forum.
