Wrist fit
Lug-to-lug decides overhang more than diameter does. Enter your wrist to see how each one should wear.
- Rolex Submariner 124060-0001 –
- Tudor Black Bay 58 7939A1A0NU-0001 –
Same rule of thumb as Watch Finder: case diameter of about 23.5% of your wrist circumference (−2 mm to +2.5 mm), and lug-to-lug no longer than about 29% of it plus 1 mm. A guide, not a rule; flat or round wrists differ.

Rolex doesn't publish the lug width of the Rolex Submariner 124060-0001, so measure it before buying a strap. The Tudor Black Bay 58 7939A1A0NU-0001 has 20 mm lugs. Size charts: Rolex size chart · Tudor lug width chart.
