C1 Jump Hour Mk V 39mm

How it wears

Wears larger than its 39 mm case suggests

Christopher Ward C1 Jump Hour Mk V 39mm measures 47.3 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is longer than 54% of the 7,413 watches in this database and longer than 49% of the 382 Christopher Ward watches listed.

A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 47.3 mm (1.86 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 14 mm thick it is on the thicker side, thicker than 80% of the watches with a listed thickness.
