Zenith G.F.J. Calibre 135 Double Signed With Naoya Hida & Co. 39.15mm

How it wears

Wears true to its 39.15 mm case size

Zenith G.F.J. Calibre 135 Double Signed With Naoya Hida & Co. 39.15mm measures 45.75 mm lug-to-lug on a 39.15 mm case, a lug-to-lug ratio of 1.17 against a database median of 1.18. That span is shorter than 67% of the 8,054 watches in this database and shorter than 80% of the 60 Zenith watches listed.

A flat wrist width of 51 mm (2.01 in) or more keeps it in the balanced range, and from 61 mm (2.40 in) it starts to look compact. Below 45.75 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 10.5 mm thick it is on the slim side, thinner than 78% of the watches with a listed thickness.
