Strap for Datejust 36 Stainless Steel / Everose / Diamond / Silver - Fluted - Diamond / Jubilee

The lug width (also called lug-to-lug distance at the attachment points) of the Datejust 36 126281RBR-0027 measures exactly 20 millimetres. This dimension defines compatibility with aftermarket straps. Any strap with a 20mm width specification will mount correctly; straps of 18mm, 22mm, or other widths will not fit the lugs of this model.

Alligator leather remains the historical and functional choice: its regular grain pattern complements rose gold tones, and its inherent durability mirrors the case's engineering. Alternatively, vegetable-tanned calf leather develops character through natural patina over years of wear. Shell cordovan in burgundy creates deliberate contrast with rose gold, whilst FKM rubber offers sports versatility without sacrificing formal elegance when needed.

To change the strap, use a spring bar tool to extract the spring bars (pins) from the lugs of the current strap. Once removed, align the new strap's spring bars with the lug holes, insert them carefully, and secure. Precision is essential to avoid scratching the case. Many qualified watchmakers and leather artisans offer this service, often included as part of strap consultation.

Yes, any strap with a 20mm lug width specification is mechanically compatible. However, to honour the engineering of a COSC-certified movement and bimetallic case, the strap should exhibit superior construction: premium leather (alligator, vegetable-tanned calf, shell cordovan), artisanal finishing, and a robust buckle ensure aesthetic and functional coherence.

A premium leather strap (alligator or vegetable-tanned calf) typically lasts 5–7 years with daily wear, developing character-rich patina in the first year. Longevity depends on exposure to perspiration, humidity, and cleaning frequency. Shell cordovan, with its denser fibrous structure, often lasts 8–10 years. Casati Milano provides an 18-month warranty against manufacturing defects, with restoration and leather regeneration services available through the atelier.
