Polo Perpetual Calendar Ultra-Thin 42mm

How it wears

Wears smaller than its 42 mm case suggests

Piaget Polo Perpetual Calendar Ultra-Thin 42mm measures 47 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.12 against a database median of 1.18. That span is shorter than 47% of the 7,421 watches in this database and shorter than 0% of the 27 Piaget watches listed.

A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 47 mm (1.85 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 8.65 mm thick it is on the slim side, thinner than 92% of the watches with a listed thickness.
