556 I 38.5mm

How it wears
Wears true to its 38.5 mm case size
Sinn 556 I 38.5mm measures 45.5 mm lug-to-lug on a 38.5 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is shorter than 68% of the 7,421 watches in this database and shorter than 80% of the 10 Sinn 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 45.5 mm (1.79 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 11 mm thick it sits within the typical range, thicker than 26% of the watches with a listed thickness.
