How it wears
Wears true to its 39 mm case size
Serica 8315 GMT 39mm measures 46.5 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is shorter than 56% of the 7,421 watches in this database and shorter than 0% of the 17 Serica watches listed.
A flat wrist width of 52 mm (2.05 in) or more keeps it in the balanced range, and from 62 mm (2.44 in) it starts to look compact. Below 46.5 mm (1.83 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 12.3 mm thick it sits within the typical range, thicker than 51% of the watches with a listed thickness.
