How it wears

Wears smaller than its 41 mm case suggests

Piaget Beta 21 41mm measures 33 mm lug-to-lug on a 41 mm case, a lug-to-lug ratio of 0.80 against a database median of 1.18. That span is shorter than 97% of the 7,413 watches in this database and shorter than 81% of the 27 Piaget watches listed.

A flat wrist width of 37 mm (1.46 in) or more keeps it in the balanced range, and from 44 mm (1.73 in) it starts to look compact. Below 33 mm (1.30 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
