The Breitling Watch Source Forums

as these questions come up quite often & the information supplied in various posts tends to "drown", here are the dimensions for these model references.

note that the cases of the 7650 Co-Pilots, the post-1969 1765 Unitimes (and the re-marked TT versions) & the 7656 Co-Pilot Top Time are not larger than the earlier models, just the bezels are quite a bit wider - but the lugs are more massive and the cases quite a lot higher, so "wear larger".

Dimensions are approximate and vary slightly between production batches or single pieces.
