Tudor Northflag GMT 40mm
9140G1A0U
How it wears
Wears larger than its 40 mm case suggests
Tudor Northflag GMT 40mm measures 48.8 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.22 against a database median of 1.18. That span is longer than 73% of the 8,093 watches in this database and longer than 54% of the 52 Tudor watches listed.
A flat wrist width of 55 mm (2.17 in) or more keeps it in the balanced range, and from 66 mm (2.60 in) it starts to look compact. Below 48.8 mm (1.92 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 12.7 mm thick it sits within the typical range, thicker than 59% of the watches with a listed thickness.

Fit reference
Fills most of the wrist for a bold, sporty fit; lug shape and end links matter.
