Alpina Seastrong Diver Extreme Automatic 39mm
Reference not provided
How it wears
Wears smaller than its 39 mm case suggests
Alpina Seastrong Diver Extreme Automatic 39mm measures 40.4 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.04 against a database median of 1.18. That span is shorter than 92% of the 8,093 watches in this database and shorter than 69% of the 16 Alpina watches listed.
A flat wrist width of 45 mm (1.77 in) or more keeps it in the balanced range, and from 54 mm (2.13 in) it starts to look compact. Below 40.4 mm (1.59 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
