Strap guide for the Rolex Datejust 36
Learn how to choose the correct strap for your Rolex Datejust 36 by understanding its case dimensions, lug width, and different material options.
Rolex · Sea-Dweller
Ref. 1366600003
The Rolex Sea-Dweller Deepsea D-Blue takes a 21 mm strap: measure between the lugs and that is the only number you need. We list 6 straps in that width. Built for water, it wears naturally on rubber or a nylon NATO; a leather strap keeps it for dry days. With a 44 mm case and 3900 m of water resistance, a thicker strap balances the case. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
Width is a starting point. Check the case and end fittings before choosing.
