Strap for Day-Date 36 White Gold / Diamond / Opal-Diamond / President

The lug width of the Rolex Day-Date 36 128349RBR-0008 is 20 millimetres. This width is characteristic of all Day-Date models in the 36mm version and is determined by the proportion between the case diameter and the geometry of the integrated lugs. Measurement should be taken with a digital calliper, positioning it between the two lugs at the lower part of the case, where the strap attaches.

For the Day-Date 36 in white gold, we recommend alligator in medium brown (havane), which creates an elegant contrast with the metal. For formal occasions, a thin black calf leather represents the most refined choice. A burgundy shell cordovan develops beautifully over time, evolving into a mahogany-red patina. The choice depends on intended use and personal colour preferences, but all these materials guarantee elegance and durability.

Changing the strap requires the use of a spring bar tool (a specific tool for removing lugs). Position the watch face down, insert the flat tip of the spring bar tool into the end of the lug, apply light pressure to compress the internal spring, then remove the old strap. Insert the new strap in the same manner, ensuring the lugs click correctly into place. If uncertain, entrust the operation to a professional.

Yes. Any strap with a 20-millimetre lug width is compatible with the Day-Date 36 128349RBR-0008. High-quality artisanal straps, such as those made from alligator, calf leather, or shell cordovan, offer an elegant alternative to original Rolex straps, allowing you to personalise your watch according to your own colour and material preferences.

The lifespan of a leather strap depends on the material, climate, and usage. A high-quality artisanal alligator or shell cordovan strap, with vegetable tanning, can last 5–10 years or more, developing a noble patina. Calf leather, more sensitive to moisture, has a lifespan of 3–7 years. Exposure to intense heat and humidity shortens durability; conversely, dry climates and moderate use extend it. Rotating between multiple straps slows wear.
