True Square Automatic Open Heart 38mm
R27086162
How it wears
Wears true to its 38 mm case size
Rado True Square Automatic Open Heart 38mm measures 44.2 mm lug-to-lug on a 38 mm case, a lug-to-lug ratio of 1.16 against a database median of 1.18. That span is shorter than 78% of the 7,413 watches in this database and shorter than 55% of the 29 Rado watches listed.
A flat wrist width of 50 mm (1.97 in) or more keeps it in the balanced range, and from 59 mm (2.32 in) it starts to look compact. Below 44.2 mm (1.74 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 9.7 mm thick it is on the slim side, thinner than 87% of the watches with a listed thickness.
