Strap for Day-Date 40 Everose / Sundust - Baguette

The Day-Date 40 in rose gold, model reference 228235-0004, features a 20mm lug width. This is the exact distance between the two lugs where the strap attaches. Verifying this measurement is essential before purchasing any aftermarket strap to ensure perfect compatibility.

For a Day-Date 40 in rose gold, alligator remains the most noble and traditional choice. It creates an impeccable formal aesthetic with natural brown tones that develop patina over time. Shell cordovan is a contemporary alternative with exceptional durability. Vegetable-tanned calf leather offers a more pronounced patina development. Even black or navy NATO canvas creates a fascinating modern contrast.

The strap is changed by removing the lugs via a small screw or pin present on each side of the case. It is advisable to entrust this task to an experienced watchmaker to avoid damage to the rose gold case. Milanostraps also offers personalised installation services at the Casati Milano atelier in Milan, by appointment.

Yes, absolutely. The strap must have an exact 20mm lug width and be crafted from premium materials—alligator, cordovan, or top-grade calf leather. A high-quality bespoke strap is not only compatible but often represents a more audacious stylistic choice compared to original Rolex straps.

A premium-quality leather strap—alligator, cordovan, or vegetable-tanned calf—typically lasts 3 to 5 years with daily wear. Longevity depends on humidity exposure, frequency of use, and maintenance. A strap from Casati Milano includes an 18-month warranty against manufacturing defects. The patina that develops over time is part of the piece's character, not a fault.
