DiaStar Original Automatic 30mm

How it wears

Wears true to its 30 mm case size

Rado DiaStar Original Automatic 30mm measures 35.6 mm lug-to-lug on a 30 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is shorter than 96% of the 7,413 watches in this database and shorter than 83% of the 29 Rado watches listed.

A flat wrist width of 40 mm (1.57 in) or more keeps it in the balanced range, and from 48 mm (1.89 in) it starts to look compact. Below 35.6 mm (1.40 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.
