Formula 1 Chronograph 43mm

How it wears

Wears smaller than its 43 mm case suggests

TAG Heuer Formula 1 Chronograph 43mm measures 48 mm lug-to-lug on a 43 mm case, a lug-to-lug ratio of 1.12 against a database median of 1.18. That span is longer than 63% of the 7,421 watches in this database and longer than 72% of the 116 TAG Heuer watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 48 mm (1.89 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 12.4 mm thick it sits within the typical range, thicker than 53% of the watches with a listed thickness.
