Strap for Day-Date 36 Yellow Gold Diamond / Green - Ombré / President - Diamond

The lug width of the Day-Date 36 128348RBR-0069 is 20 millimetres. This historic measurement is specific to the Rolex President and is determined by the distance between the upper and lower fixing pins. It is essential to verify this dimension when ordering an aftermarket strap, as 20 millimetres is not a standard specification on modern or sports models.

For a yellow gold 18K Day-Date 36, alligator leather represents the most traditional and formal choice, particularly in tight-pore cuts. Shell cordovan offers a soft patina and controlled lustre that evolves over time. Vegetable-tanned calf leather constitutes a contemporary alternative permitting deeper colour personalisation. A vulcanised rubber strap also maintains the elegance of the case without functional compromise.

To change the Day-Date 36 strap, you must use a specific tool (spring bar tool) to compress the fixing pins and remove the old lug. The pins must be inserted into the appropriate slots beneath the case terminals, respecting the correct orientation. We recommend having this operation performed by a certified watchmaker to avoid scratches to the yellow gold case or damage to internal mechanisms.

The lifespan of a leather strap depends on usage and material type. High-quality alligator reaches 3-4 years with daily wear; shell cordovan, due to its natural density, can last up to 5-6 years; vegetable-tanned calf leather lasts on average 2-3 years. Natural ageing is part of the beauty of leather: a rich patina and controlled creasing tell the story of your time with the watch.

Any strap with a 20-millimetre lug width is technically compatible, but aesthetic and constructive choice remains essential. A low-quality strap diminishes the elegance of the yellow gold case and COSC-certified movement. We recommend straps in alligator, cordovan, calf or rubber of proven durability, selected from artisans specialising in ensuring finishes and colours coherent with your watch vision.
