How it wears
Wears true to its 39.5 mm case size
Gronefeld 1941 Principia 39.5mm measures 46.9 mm lug-to-lug on a 39.5 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is shorter than 53% of the 7,413 watches in this database.
A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 46.9 mm (1.85 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
