Grand Lady Kalla 19.4mm

How it wears

Wears larger than its 19.4 mm case suggests

Vacheron Constantin Grand Lady Kalla 19.4mm measures 30.1 mm lug-to-lug on a 19.4 mm case, a lug-to-lug ratio of 1.55 against a database median of 1.18. That span is shorter than 98% of the 7,421 watches in this database and shorter than 94% of the 34 Vacheron Constantin watches listed.

A flat wrist width of 34 mm (1.34 in) or more keeps it in the balanced range, and from 41 mm (1.61 in) it starts to look compact. Below 30.1 mm (1.19 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 8.3 mm thick it is on the slim side, thinner than 93% of the watches with a listed thickness.
