Strap for Day-Date 36 Platinum Domed / President / Ice Blue Computer

The lug width of the Rolex Day-Date 36 118206-0017 is 20mm. The lugs feature a curved profile requiring straps with shaped ends to ensure proper fitment against the solid platinum 950 case.

For the platinum Day-Date 36, a 20mm curved-end alligator strap with vegetable tanning is the most appropriate choice, both aesthetically and in terms of longevity. Shell cordovan is a refined alternative that develops a distinctive patina over time. A deployant clasp is recommended to distribute pressure evenly and preserve the strap's structure.

Strap replacement requires a springbar tool to release the spring bars from the lugs. It is advisable to work on a protective cushion to avoid scratches on the platinum case. The original Rolex spring bars measure 20mm and can be reused with compatible aftermarket straps.

Yes. 20mm curved-end aftermarket straps are fully compatible with the Rolex Day-Date 36 118206-0017. Milanostraps.it offers a curated selection of handcrafted leather, cordovan and rubber straps with the correct lug geometry for this model, produced by Casati Milano using selected materials.

The lifespan of a leather strap depends on the material and care routine. A quality vegetable-tanned alligator strap, worn daily with moderate frequency, retains structural integrity for 3 to 5 years. Shell cordovan can exceed 5 years whilst developing a characteristic patina. It is advisable to rotate between at least two straps and allow the unused one to dry and recover its shape.
