Black Bay 58 39mm
M79030N-0001
How it wears
Wears larger than its 39 mm case suggests
Tudor Black Bay 58 39mm measures 47.8 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.23 against a database median of 1.18. That span is longer than 60% of the 7,421 watches in this database and longer than 52% of the 52 Tudor watches listed.
A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 47.8 mm (1.88 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
At 11.9 mm thick it sits within the typical range, thicker than 42% of the watches with a listed thickness.
