Top Time B31 38mm

How it wears

Wears true to its 38 mm case size

Breitling Top Time B31 38mm measures 45.8 mm lug-to-lug on a 38 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is shorter than 66% of the 7,413 watches in this database and shorter than 78% of the 298 Breitling watches listed.

A flat wrist width of 51 mm (2.01 in) or more keeps it in the balanced range, and from 62 mm (2.44 in) it starts to look compact. Below 45.8 mm (1.80 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 10.3 mm thick it is on the slim side, thinner than 82% of the watches with a listed thickness.
