Strap for Datejust 36 Rolesor Yellow Diamond / Jubilee / Black Computer

The lug width of the Rolex Datejust 36 116243-0015 is exactly 20 millimetres. This specification determines strap compatibility: any strap for this model must have a width of precisely 20mm between the case lugs. To verify accurately, use a digital calliper to measure the internal space between the lugs (metal attachment points on the case).

Alligator leather with fine grain remains the traditional choice for the two-tone Datejust 36: the regular texture and natural lustre enhance the case's classical proportions. Alternatively, calf leather with vegetable tanning offers a more pronounced grain and develops a distinguished patina over time. For sport-oriented options, heavyweight cotton NATO straps or FKM rubber maintain solidity without aesthetic compromise.

The Datejust 36 strap is attached to the case via spring bars (pass-through pins). To replace it, remove the old strap using a spring bar removal tool to extract the pins, then insert the new strap's pins ensuring they align correctly within the case lugs. If uncertain, consult a professional watchmaker.

Yes, absolutely. The Rolex Datejust 36 with 20mm lugs is compatible with any high-quality artisanal strap manufactured for this measurement. A premium aftermarket strap in alligator, calf, or rubber can actually enhance the watch's proportions and offer greater aesthetic versatility compared to the original strap.

The lifespan of a leather strap depends on usage and care: a quality alligator strap typically lasts 3–4 years with daily wear, up to 5–6 years with occasional use. Calf leather with vegetable tanning tends to develop patina and age gracefully, maintaining functionality beyond 4 years. Casati Milano's guarantee on manufacturing defects is 18 months.
