GMT-Master II 40mm
126710BLNR
How it wears
Wears true to its 40 mm case size
Rolex GMT-Master II 40mm measures 48 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is longer than 63% of the 7,413 watches in this database and longer than 58% of the 50 Rolex watches listed.
A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 48 mm (1.89 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 mm thick it sits within the typical range, thicker than 45% of the watches with a listed thickness.
