Strap for Datejust 36 Stainless Steel / Yellow Gold / Fluted / Champagne Diamond / Jubilee

The lug width is 20 millimetres. This measurement represents the distance between the two case attachments where the strap fits. It is specific to the Datejust 36 and incompatible with Rolex sports models that feature wider lugs (22mm or 24mm).

Genuine alligator is the traditional choice for the Datejust 36. Optimal thickness is 1.4 millimetres for the quills and 1.8 for the body. Vegetable-tanned calf and Japanese shell cordovan are also excellent for elegance and longevity. NATO and FKM rubber offer sportive versatility.

The strap is replaced using a spring bar that protrudes from the case attachment. Secure the watch in a softjaw vise, carefully remove the spring bar with a spring bar tool, slide out the old strap and insert the new one. The operation requires precision to avoid scratching the case.

Yes, provided the lug width is exactly 20 millimetres and the spring bars are military-grade stainless steel (316L). A certified artisanal strap guarantees construction tolerance below 0.5 millimetres, preventing lateral play and premature wear of the attachments.

An alligator or vegetable-tanned cordovan lasts between 4 and 6 years of daily wear, provided it receives routine maintenance (wiping with a soft cloth, protection from prolonged humidity, annual conditioning). FKM rubber lasts 3-5 years. Waxed calf, with natural patina, has longevity extending to 7 years.
