1815 Chronograph 39.5mm

How it wears

Wears larger than its 39.5 mm case suggests

A. Lange & Söhne 1815 Chronograph 39.5mm measures 48.4 mm lug-to-lug on a 39.5 mm case, a lug-to-lug ratio of 1.23 against a database median of 1.18. That span is longer than 70% of the 7,421 watches in this database and longer than 69% of the 32 A. Lange & Söhne watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 65 mm (2.56 in) it starts to look compact. Below 48.4 mm (1.91 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.
