Strap for Datejust 36 Stainless Steel / Everose / Fluted / Black Diamond / Jubilee

The Rolex Datejust 36 reference 126231-0019 features a 20mm lug width. This measurement, also known as lug-to-lug spacing or ansa width, is the distance between the two spring bar holes on the watch case. Verifying this dimension is essential before purchasing an aftermarket strap to ensure proper fit and compatibility with your timepiece.

For the Datejust 36 in stainless steel and rose gold, we recommend three primary options: brown or black alligator for a formal, sophisticated aesthetic; vegetable-tanned calf leather for those preferring a softer, contemporary feel with natural patina development; or shell cordovan in cognac for collectors seeking rich colour evolution over time. FKM rubber straps remain the versatile choice for everyday, sporty wear.

Strap replacement requires a spring bar tool—a small, tapered instrument designed to manipulate the spring bars securing the strap to the case lugs. Place your watch on a soft surface, locate the tiny slots on the underside of each lug, insert the tool to compress the spring bar, then carefully withdraw the old strap and insert the new one. If you lack experience, consult an authorised Rolex service centre or a qualified watchmaker.

Absolutely. Numerous high-quality aftermarket options exist for 20mm lugs. Artisanal leather straps offer superior aesthetic and tactile qualities compared to the original bracelet. Specialist manufacturers produce hand-finished straps with custom deployante clasps and bespoke detailing. Always verify that your chosen strap has compatible lug bars and that the width precisely measures 20mm for optimal fit.

A leather strap's lifespan depends on tannage type, wear patterns, and maintenance practices. A high-quality alligator strap typically lasts 3–5 years under moderate daily use, whilst calf or shell cordovan can reach 4–6 years. Best practice is to rotate straps to distribute wear evenly and allow complete drying after moisture exposure. Vegetable-tanned leather straps develop a rich natural patina that enhances character over time.
