Strap for Datejust 31 Stainless Steel/ Rose Gold / Domed / Chocolate - Roman / Oyster

The lug width of the Rolex Datejust 31 278241-0003 is 16mm. This measurement represents the distance between the two lugs where the strap is inserted. It is essential to verify this specification before ordering an aftermarket or bespoke strap to ensure a perfect fit.

For a Datejust 31 in Rolesor Everose, we recommend premium leather straps such as alligator or vegetable-tanned calf leather, which honour the elegance of the two-tone case. A dark-patina alligator strap creates contrast with rose gold, whilst vegetable-tanned calf offers versatility. Alternatively, an Oystersteel bracelet reproduces the authenticity of the original configuration.

Strap replacement requires a dedicated spring bar remover tool. Position the watch in a protective holder, locate the pins connecting the lugs to the case, gently press inward to release them, and slide off the old strap. Insert the new strap by aligning the terminal holes with the pins, then repeat on the opposite side. If you lack experience, consult an authorised service centre.

Yes, provided they meet the 16mm lug width specification. Bespoke aftermarket straps of Haute Couture quality, such as those by Casati Milano, are fully compatible and offer personalisation beyond standard market offerings. Always verify that the case spring bar diameter (typically 1.8mm) matches the strap terminal holes.

Durability depends on leather quality, daily usage, and maintenance. A premium alligator or shell cordovan strap with vegetable tanning, hand-crafted construction, maintains structural integrity for 3–5 years of regular wear. Humidity, perspiration, and UV exposure accelerate ageing. Casati Milano offers an 18-month warranty against manufacturing defects and recommends periodic maintenance to extend strap lifespan.
