Strap for Datejust 36 Rolesor Everose Domed / Oyster / Black MOP

The lug width of the Rolex Datejust 36 reference 116201-0079 is 20 millimetres. This measurement refers to the distance between the terminals of the lug itself—the small metal attachments that connect the case to the strap. Accurate measurement with a calliper or ruler is essential before ordering a compatible strap, ensuring precise mechanical fit and secure closure.

For the Datejust 36 116201-0079, alligator leather represents the most aesthetically coherent choice: its characteristic grain dialogue naturally with the mother-of-pearl texture. Alternatively, polished black calf leather offers formal elegance without competing with the dial. For those preferring temporal evolution, cognac-coloured shell cordovan develops a profound patina over time, transforming the strap into a personal archive of wear.

To change the strap on the Datejust 36, use a spring bar removal tool to gently extract the suspension pins that link the strap to the case lugs. Position the tool beneath the lug terminal, apply gentle pressure to release the pin, and repeat on the opposite side. Align the new strap's holes with the pins and press until you hear the security click. If uncertain, Casati Milano provides this service by appointment.

Yes, any strap with a 20-millimetre lug width is mechanically compatible. However, to preserve the aesthetic integrity and value of a two-tone watch with mother-of-pearl dial, choose materials and finishes equivalent to the watch's quality—alligator, calf, or shell cordovan from specialised artisans, not generic synthetic straps. An artisanal Italian strap ensures coherence with the watch's manufacturing standard.

A quality leather strap (alligator, calf, shell cordovan), worn daily, typically lasts 3 to 5 years before replacement. This variability depends on environmental exposure (perspiration, humidity, UV), frequency of wear, and leather type. Shell cordovan, with its corded grain structure, tends to last longer owing to natural density. Vegetable-tanned leather does not accelerate wear but modifies the ageing profile, developing patina more rapidly. Periodic maintenance—gentle cleaning, protection from extreme humidity—significantly extends longevity.
