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

The Rolex Datejust 36 reference 26233-0036 features integrated lugs with a width of 20 millimetres. This measurement is the standard for the 36mm case in two-tone configuration (yellow gold and steel). To verify strap compatibility, measure from one lateral pin to the opposite lateral pin: the result must be exactly 20mm.

For the Datejust 36 in yellow gold and steel, we recommend black or dark brown alligator leather with vegetable tanning for formal occasions, or bull calf leather for more versatile daily wear. Shell cordovan remains the supreme choice for those seeking a leather with evolving patina over time. All straps must feature 20mm lug width and spring bars proportional to the 36mm case diameter.

Extract the lateral pins (lugs) using a dedicated spring bar tool to avoid damage to the case. Align the new strap's passants with the lugs, then reinsert the pins until you feel the locking click. If you lack expertise, it is advisable to consult a certified watchmaker or visit Casati Milano atelier for professional installation.

Yes, you may install a quality artisanal leather strap provided it respects the 20mm lug width specification. A fine leather strap crafted by experienced artisans and featuring adequate spring bars does not compromise your Rolex's value and broadens its aesthetic versatility. Avoid overly economical straps or those with poor dimensional tolerances.

A fine leather strap—alligator, calf leather, or cordovan—with vegetable tanning and artisanal construction typically lasts 3 to 7 years of daily use, depending on exposure to humidity, sunlight, and mechanical wear. Proper maintenance—periodic cleaning and conditioning with natural oils—significantly extends longevity. Casati Milano offers an 18-month warranty on manufacturing defects and provides guidance for strap preservation.
