Strap for Day-Date 36 Yellow Gold Diamonds / Oyster / White Roman

The lug width of the Rolex Day-Date 36 reference 118388-0101 is 20 millimetres. This measurement represents the perpendicular distance between the two metal pins that emerge from the case and attach the strap. Always verify this measurement using a digital calliper before ordering an aftermarket strap, as a deviation of just a few millimetres will compromise both aesthetic fit and wearing comfort.

For the Day-Date 36 in yellow gold 118388-0101, alligator remains the most harmonious choice: the natural texture of American crocodile enhances the warmth of the gold case. Burgundy shell cordovan offers profound colour depth and a patina that matures with age. Tuscan calf leather guarantees fine grain and compact structure, ideal for formal contexts. Natural rubber with leather backing presents a versatile option for daily wear without compromising sophistication.

The procedure requires a dedicated tool (spring bar tool) to remove the elastic pins that secure the strap to the case lugs. Position the watch on a soft surface, gently insert the tool into the small slot beneath the pin, apply light pressure until the pin retracts, then withdraw the worn strap. Reverse the procedure to install the new strap, ensuring the pins lock completely in both lugs. If inexperienced, entrust the task to an authorised service centre to prevent damage.

Yes, any strap with a 20-millimetre lug width is compatible with the 118388-0101, provided the strap is constructed with rigorous precision. Certified artisanal leather straps in Italian leather, alligator or shell cordovan offer superior quality and longevity compared to industrial products. Always verify that the elastic pins (spring bars) are of correct length for the case lugs.

A high-quality artisanal leather strap (alligator, calf or shell cordovan), subjected to moderate daily wear, maintains structural integrity for 3–5 years. Actual lifespan depends on humidity exposure, frequency of wear and maintenance care (leather cleaner, rain protection). Vegetable tanning develops patina over years, consolidating the strap rather than degrading it. Regular maintenance (gentle cleaning, air drying, natural protective product) significantly extends useful life to 7–10 years.
