Strap for Datejust 36 Stainless Steel Fluted / Jubilee / Rhodium Wave

The lug width of the Rolex Datejust 36 116234-0159 is 20mm. This measurement represents the distance between the two centre holes on the case where the lugs attach. To verify this measurement, measure precisely the space between the lugs: it must be exactly 20mm to ensure compatibility with aftermarket straps.

For the Datejust 36 two-tone (white gold and steel) the strap in dark brown alligator or cognac calf are the classic choices. Alligator maintains formal elegance with its fine grain and natural lustre; calf leather in vegetable tanning develops a rich patina over time, mirroring the patina of aged white gold. The choice depends on intended use and personal colour preferences.

To change the strap you will need two specialist tools: a lug removal tool and a protective work surface for the case. Insert the removal tool into the small hole on each lug, gently pushing the pin that secures the lug to the case. Once both lugs are removed, you can remove the original strap and install the new one, ensuring the lugs fully engage in the lug slots. If you are not experienced, it is advisable to have the operation carried out by a professional watchmaker.

Yes, you can use compatible 20mm aftermarket straps on the Datejust 36 116234-0159, provided they respect the exact dimensions of the lug width. Quality artisanal straps (in alligator, calf, shell cordovan) maintain the aesthetic and constructive coherence of the original Rolex. Always verify that the strap has an integrated deployant clasp or is compatible with Rolex lugs.

The lifespan of a leather strap depends on the material, use and environmental conditions. A quality artisanal alligator strap can withstand 5-7 years of daily wear; vegetable-tanned calf 4-6 years; shell cordovan 6-8 years due to greater material density. Exposure to sweat, water and sunlight accelerates ageing. A well-maintained strap (protected from excessive moisture and stored in dry environments) maintains functionality longer.
