Strap for Day-Date 36 Platinum - Baguette / Bright Blue - Baguette / President

The Rolex Day-Date 36 reference 128396TBR-0024 in platinum requires a strap with a lug width (ansa) of precisely 20 millimetres. To verify the measurement with absolute accuracy, measure the distance between the two metal lugs (the points where the strap inserts): it must be exactly 20mm. An incorrect measurement results in total incompatibility, so we strongly recommend verification before any purchase.

For the Day-Date 36 128396TBR-0024 in platinum, genuine alligator (Alligator mississippiensis) represents the most appropriate choice: its natural grain creates a tactile dialogue with the platinum case finishing, and the patina that develops over time adds character. Premium alternatives include vegetable-tanned calf leather for a more uniform texture, or shell cordovan for an almost metallic density. Avoid synthetics and nylon: the nobility of platinum deserves natural materials.

Changing the strap on a Day-Date 36 requires specific tools: a spring bar tool (two-ended lever) to compress the tiny springs that retain the lug pins. Secure the watch in a padded vice, insert the lever into the pin slot, compress the internal spring and gently extract it. Repeat on the other side, then position the new strap by aligning the pins with the holes and releasing the spring. We recommend having this operation performed by an authorised Rolex dealer or specialist watchmaker to prevent damage.

Yes, provided the aftermarket strap strictly respects the 20-millimetre lug width. A high-quality artisanal strap—crafted in alligator, calf leather or shell cordovan—is not only compatible but adds personality and aesthetic flexibility to your timepiece. MilanoStraps offers a curated collection of 20mm straps specifically selected for Rolex and luxury watches, with customisation options available at the Casati Milano atelier.

The durability of a leather strap depends on the material, frequency of use and maintenance. A quality alligator strap, subject to normal wear (3–4 days per week), has an average lifespan of 4–6 years before showing visible signs of deterioration. Shell cordovan, more resilient, can reach 7–8 years. Vegetable-tanned leather ages more predictably and develops a characteristic patina. To extend the strap's life, avoid prolonged water exposure, clean periodically with a damp cloth and store in dry environments. A replacement and restoration service at Casati Milano ensures a new life for your piece.
