Reef 39.5mm Automatic COSC 300M
2201.1.6300.910 · Green
How it wears
Wears true to its 39.5 mm case size
Formex Reef 39.5mm Automatic COSC 300M measures 45.5 mm lug-to-lug on a 39.5 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is shorter than 68% of the 7,413 watches in this database and shorter than 69% of the 67 Formex watches listed.
A flat wrist width of 51 mm (2.01 in) or more keeps it in the balanced range, and from 61 mm (2.40 in) it starts to look compact. Below 45.5 mm (1.79 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.
