Montblanc 1858 Minerva Monopusher Chronograph "Blue Arrow" P.05 for Collective Horology 42mm

How it wears

Wears larger than its 42 mm case suggests

Montblanc 1858 Minerva Monopusher Chronograph "Blue Arrow" P.05 for Collective Horology 42mm measures 51.5 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.23 against a database median of 1.18. That span is longer than 93% of the 8,010 watches in this database.

A flat wrist width of 58 mm (2.28 in) or more keeps it in the balanced range, and from 69 mm (2.72 in) it starts to look compact. Below 51.5 mm (2.03 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 12.5 mm thick it sits within the typical range, thicker than 56% of the watches with a listed thickness.
