Strap for Datejust 36 Rolesor Yellow Diamond / Oyster / Champagne

The lug width of the Rolex Datejust 36 reference 116243-0030 is precisely 20mm. This measurement represents the distance between the two attachment lugs on the case and is fundamental for strap compatibility. Any strap intended for this model must feature a 20mm lug width to ensure a secure fit without gaps or forcing.

The best strap depends on intended use and personal preference. Genuine alligator is the most refined choice, particularly in dark brown or black, as it harmonises naturally with the two-tone yellow gold and steel case. Shell cordovan offers an excellent balance between structure and flexibility, developing a captivating patina over time. For daily versatility, vegetable-tanned calf in cognac is ideal, whilst navy NATO adds a modern sporty character. The recommended buckle is a deployante in yellow gold or steel.

Changing the strap on a Datejust 36 requires two small tools: a spring bar remover or thin blade. Insert the tool into the lateral spaces between the lug and the strap to compress the small internal springs (spring bars) that secure the strap in place. Once the springs are released on one side, the strap slides away. Reversing the procedure, attach the new strap ensuring the springs lock correctly on both sides. If you are not entirely confident, it is advisable to have a qualified watchmaker perform the operation.

All artisanal straps with a 20mm lug width are compatible with the Rolex Datejust 36 116243-0030, regardless of brand. Compatibility depends solely on lug width: 20mm in this instance. Options include alligator, crocodile, shell cordovan, calf, suede, NATO textile and rubber. It is important to select a strap of elevated manufacturing quality, designed for luxury watches, so that the finish and closure solidity (buckle or deployante) matches the standard of the Rolex.

The lifespan of a leather strap depends on the type of leather, usage and maintenance. Genuine alligator and shell cordovan, being denser and more structured hides, typically last between 8 and 12 years with moderate-regular use. Calf is more delicate and typically resists between 4 and 8 years. Factors that shorten lifespan include prolonged moisture exposure, frequent perspiration and lack of rotation with other straps. Conscious maintenance—drying the strap if wet, avoiding prolonged humidity—significantly extends longevity. Many collectors choose aftermarket straps precisely for this reason: they allow rotation of the primary strap, preserving it.
