Strap for Datejust 36 Stainless Steel Diamond / Jubilee / Blue Roman

The lug width (ansa) of the Rolex Datejust 36 ref. 116244-0071 is precisely 20 millimetres, measured inner-to-inner between the two attachment points on the case. This dimension is specific to this model and ensures a harmonious proportion between the 36mm case diameter and the wrist. Only 20mm straps are compatible with this reference.

For this reference, alligator leather in vegetable tanning represents the pinnacle of elegance: the fine grain texture complements the minimalist proportions of the case. Shell cordovan develops a unique patina over time, transitioning from burgundy to deep brown. Vegetable-tanned calf leather suits those seeking a strap rich with character and history. Rubber or NATO straps maintain versatility for sportier contexts without compromising the dress watch aesthetic.

Strap replacement is performed using the springbars—spring-loaded pins that connect the strap to the case lugs. With a dedicated springbar tool, press the terminal of the spring bar inward, allowing the strap to slide out of the lug. Repeat on the other side. Insert the new strap into the spring mechanism and slide until you hear the secure 'click'. This procedure is accessible to most users, though Casati Milano offers professional service by appointment if you prefer guaranteed execution.

Yes, any strap with a 20mm lug width is compatible with the Datejust 36 ref. 116244-0071, regardless of manufacturer. The critical factor is verifying the lug width is exactly 20mm—many artisan-made straps in alligator, cordovan, and vegetable-tanned calf offer superior quality to Rolex factory bracelets. Casati Milano specialises exclusively in this specific size, with bespoke finishing and personalised leather selection.

Durability depends on material and usage frequency. An artisanal alligator or vegetable-tanned calf strap typically lasts 3–4 years under daily wear, developing distinctive patina. Shell cordovan, owing to its density, can exceed 5–6 years whilst retaining elasticity. A rubber or FKM strap lasts 2–3 years before showing signs of hardening. Casati Milano provides an 18-month warranty against manufacturing defects; natural leather wear is part of the charm and personalisation of your watch over time.
