Strap for Datejust 36 Stainless Steel / Yellow Gold / Fluted / Champagne - Fluted / Oyster

The lug width (ansa width) of the Rolex Datejust 36 reference 126233-0040 is 20mm. This measurement corresponds to the distance between the inner shoulders of the lug where the strap attaches. It is essential to verify this dimension before purchasing an aftermarket strap, as an incorrectly sized spring bar will not fit properly to the case.

Natural alligator is the most recommended choice for the Rolesor two-tone: the grain complements the yellow gold elegantly without competing visually. Shell Cordovan offers structural rigidity and a profound lustre that develops character with age. Vegetable-tanned calf provides immediate softness and a fine grain that does not distract from the case. We advise against canvas NATO straps, as the Rolesor deserves the sophistication of full-grain leather.

To change the strap, position your watch on a soft surface. Use a dedicated spring bar tool to press the internal springs of the lugs and extract the current strap. The procedure requires care to avoid scratching the case. Align the new strap ends with the lug and press firmly until you hear the spring bars click into place. If you are inexperienced, we recommend entrusting the task to an official Rolex service centre or a specialised atelier.

All straps with a 20mm lug width are compatible with the 126233-0040. This includes various leather types (alligator, Shell Cordovan, calf, suede), multiple colours, and different buckle finishes (from stainless steel deployantes to gold examples). Compatibility is guaranteed by the standard lug width; aesthetics and quality depend on the manufacturer. We recommend artisanal full-grain leather straps to preserve the authority of the Rolesor case.

A quality artisanal leather strap typically lasts 3–5 years with daily wear, depending on the leather quality and climate conditions. Alligator tends to last longer due to the hide structure; calf is softer initially but may weaken earlier. Exposure to perspiration, humidity and sunlight accelerates wear. Regular maintenance—gentle cleaning and occasional conditioning—significantly extends the strap's longevity.
