Strap for Datejust 36 Everose Strap Black Mother of Pearl Diamonds

The lug width of the Rolex Datejust 36 116185-0004 is 20 millimetres. This measurement represents the outer diameter of the metal tube affixed to the case, measured centre-to-centre of the two attachment holes. A lug width of 20mm is specific to this model and determines compatibility with any aftermarket or bespoke strap.

For the Datejust 36 116185-0004 in rose gold, the ideal materials are genuine alligator with natural luminous patina (cognac or chocolate brown), shell cordovan for those seeking evolved character, or vegetable-tanned calf for constructive simplicity. Alligator represents the formal choice par excellence, whilst cordovan suits collectors desiring a strap capable of profound patina development over time. All must feature a 20mm lug width.

To change the strap, use a spring bar tool to compress the metal pins (spring bars) that secure the strap to the lugs. Position the tool beneath the lug, compress the internal spring, and gently extract the old strap. Repeat the procedure with the new 20mm-width strap. It is recommended to work on a soft surface to avoid scratches to the rose gold case. Alternatively, consult a professional watchmaker to ensure accuracy.

Yes, any strap featuring a 20mm lug width is compatible with the 116185-0004, regardless of manufacturer provenance. Compatibility depends exclusively on lug width and the diameter of the attachment holes. Casati Milano artisanal straps, available in the 20mm collection, guarantee construction quality equivalent to original Rolex straps, with the advantage of aesthetic and material personalisation.

A high-quality leather strap, such as natural alligator or vegetable-tanned shell cordovan, has an average lifespan of 5–8 years with daily wear, varying according to humidity exposure, climate and frequency of use. Alligator leather tends to endure longer due to superior fibre density. A Casati Milano strap, crafted with certified leather and professional finishing, includes an 18-month warranty against manufacturing defects. Actual longevity depends on proper maintenance, periodic cleaning and protection from chemical solvents.
