Naoya Hida & Co. Type 8A 31mm

How it wears

Wears larger than its 31 mm case suggests

Naoya Hida & Co. Type 8A 31mm measures 38.4 mm lug-to-lug on a 31 mm case, a lug-to-lug ratio of 1.24 against a database median of 1.18. That span is shorter than 94% of the 8,093 watches in this database.

A flat wrist width of 43 mm (1.69 in) or more keeps it in the balanced range, and from 52 mm (2.05 in) it starts to look compact. Below 38.4 mm (1.51 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 8.9 mm thick it is on the slim side, thinner than 89% of the watches with a listed thickness.
