Strap for Day-Date 36 Platinum - Fluted / White - Roman / President

The lug width of the Rolex Day-Date 36 128236-0017 is 20 millimetres. This specification is exclusive to Day-Date models in the 36mm case size and requires watch straps engineered to this precise width. It is essential to verify the internal distance between the case lugs before ordering an aftermarket strap to ensure material compatibility.

African alligator with fine grain represents the primary choice for the platinum Day-Date 36: the textured surface of the skin creates an elegant visual contrast with the coolness of the metal and develops a sophisticated patina over time. Shell cordovan stands as an alternative of absolute prestige, with superior ageing characteristics and progressively richer tonalities. For daily versatility, a dark brown alligator maintains formality without compromise.

Strap replacement requires a dedicated tool (spring bar tool) to remove the elastic pins that secure the strap to the case lugs. It is critical to operate with precision to avoid scratching the platinum lugs: we recommend using a soft cloth during the procedure. Alternatively, a specialised watchmaker can complete the operation within minutes without risk of damage.

Yes, provided the strap is engineered specifically for a 20-millimetre lug width. High-quality artisanal aftermarket straps — crafted in alligator, cordovan, or structured rubber — fit seamlessly with the standard Rolex attachment system, delivering equivalent functionality and greater aesthetic freedom. Always verify that the passants are calibrated for 20mm prior to purchase.

A high-quality artisanal leather strap typically lasts 3–5 years with daily wear, provided appropriate maintenance is observed: avoid prolonged moisture exposure, dry it promptly after incidental water contact, and periodically apply a conditioner formulated for noble leathers. Alligator skin and cordovan age more gracefully and develop attractive patina even beyond 5 years. Casati Milano provides an 18-month warranty on manufacturing defects for every custom-made strap.
