Strap for Day-Date 36 Everose Gold - Fluted / Turquoise / President

The lug width of the Rolex Day-Date 36 128235-0064 is exactly 20 millimetres. This measurement corresponds to the distance between the two horizontal pins integrated into the case. It is critical to respect this dimension when selecting a compatible strap, as 19 mm or 21 mm lugs would cause installation difficulties and mechanical stress on the case.

Alligator remains the finest natural material for the Day-Date 36 in rose gold. A fine-grain alligator in dark brown, cognac, or black is recommended. For summer wear, vegetable-tanned calf leather offers superior breathability whilst maintaining formal elegance. Shell Cordovan is an excellent choice for those seeking a patina that evolves over time, developing natural warmth. NATO fabric straps are unsuitable and conflict with the model's aesthetic proposition.

Strap replacement is performed by removing the two lateral support bars (spring bars) using a specialised tool, inserting the new bars into the new strap, and securing them within the integrated lugs of the case. It is advisable to entrust this operation to a qualified watchmaker or specialist atelier, to avoid scratching the rose gold case. Casati Milano offers professional installation service at its Milan atelier.

Yes, provided the strap is specifically designed for a 20mm lug width and features terminal curvature compatible with Rolex's integrated lugs. Artisanal quality straps (natural leather, hand-finished) maintain the aesthetic and constructive integrity of the watch. Always consult the manufacturer to verify technical compatibility specifications.

The lifespan of a natural leather strap varies depending on frequency of use, climate, and care. On average, a fine artisanal alligator or calf leather strap lasts 3–5 years of daily wear, sometimes longer if subjected to regular maintenance and protected from prolonged water exposure or UV radiation. Casati Milano straps include an 18-month warranty against manufacturing defects.
