Grand Seiko Evolution 9 Collection 5 Day Diver's 200m "Ushio" 43.8mm
SLGA023
How it wears
Wears true to its 43.8 mm case size
Grand Seiko Evolution 9 Collection 5 Day Diver's 200m "Ushio" 43.8mm measures 51.5 mm lug-to-lug on a 43.8 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is longer than 93% of the 8,010 watches in this database and longer than 94% of the 232 Grand Seiko watches listed.
A flat wrist width of 58 mm (2.28 in) or more keeps it in the balanced range, and from 69 mm (2.72 in) it starts to look compact. Below 51.5 mm (2.03 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 13.8 mm thick it is on the thicker side, thicker than 79% of the watches with a listed thickness.
Wrist fit analyzer
Fit reference
Uses nearly the full wrist width; trying the watch on is strongly recommended.
