SUB 300 Professional 42.5mm
821.10.351.21
How it wears
Wears smaller than its 42.5 mm case suggests
Doxa SUB 300 Professional 42.5mm measures 45 mm lug-to-lug on a 42.5 mm case, a lug-to-lug ratio of 1.06 against a database median of 1.18. That span is shorter than 70% of the 7,413 watches in this database and shorter than 50% of the 320 Doxa watches listed.
A flat wrist width of 50 mm (1.97 in) or more keeps it in the balanced range, and from 60 mm (2.36 in) it starts to look compact. Below 45 mm (1.77 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 13.4 mm thick it sits within the typical range, thicker than 69% of the watches with a listed thickness.
