Frequently asked questions

What is the lug width of the Rolex Datejust 36 reference 116231-0087?

The lug width of the Rolex Datejust 36 reference 116231-0087 is 20 millimetres. This measurement is the fundamental parameter for identifying compatible straps. It is measured perpendicularly between the two lugs, not on the strap passant.

Which strap is most suitable for the Datejust 36 two-tone rose gold and stainless steel?

For a two-tone Datejust 36, alligator remains the finest choice, preferably in dark tones such as black, dark brown, or burgundy. Vegetable-tanned calf leather represents the versatile alternative that develops patina naturally. Avoid rose gold straps which would create visual imbalance; prefer stainless steel for passant and buckle.

How do you change the strap on a Rolex Datejust 36?

Strap replacement requires specialist tools: a spring bar remover and a clean work surface. The spring bars must be gently removed from the lug terminators, the old strap extracted, and the new strap aligned before the bars are reinserted. If inexperienced, it is advisable to entrust the operation to a certified watchmaker to prevent damage.

Is an aftermarket strap compatible with the Rolex Datejust 36 116231-0087?

Yes, any strap with a 20-millimetre lug width is physically compatible. We recommend artisanal high-quality straps (alligator, calf, shell cordovan) from certified ateliers, which guarantee noble materials and precise workmanship. Avoid cheap generic straps that would diminish the watch.

How long does a leather strap last on a Datejust 36?

A premium leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with ordinary maintenance. Longevity depends on frequency of wear, moisture exposure, and tanning quality. A vegetable-tanned calf strap, though visibly aged, remains functional for 5–7 years. Artisanal warranty covers manufacturing defects for 18 months.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
