Day-Date 36 128348RBR-0068— lug 20mm

The Rolex Day-Date 36 reference 128348RBR-0068 features a 20-millimetre lug width. This specification is standard across all Day-Date 36 models in yellow gold, platinum and Oystersteel. Always verify your watch's reference number before ordering a strap, as Day-Date 40 models require a 22-millimetre lug width.

For a yellow gold dress watch, crocodile leather in dark tones (black, dark brown) or vegetable-tanned calf offers the most refined aesthetic. Crocodile delivers sartorial elegance without competing with the metal's lustre, whilst vegetable-tanned calf develops a rich patina over time that mirrors the noble ageing of gold. We recommend avoiding Nile crocodile for this model, as the pronounced grain pattern diminishes the understated character of the Presidential.

The Day-Date 36 is fitted with an Oyster-style buckle equipped with removable spring bars. Place the watch face-down on a soft surface, locate the small metal pin beneath the lug, then use a spring bar tool to press the pin towards the centre and extract the strap. Repeat on the opposite side. Insert the new strap by aligning the tips with the lugs, then ensure the spring bars click firmly into place.

Yes. Any strap with a 20-millimetre lug width is compatible, provided the buckle's internal width does not exceed 18 millimetres to fit correctly within the case lugs. Genuine leather, sports rubber and technical fabrics are common alternatives. The essential criterion is that the strap sits flush with the case sides, preserving the balanced proportions of the Presidential design.

A quality leather strap with vegetable tanning and artisanal construction typically lasts between 18 and 36 months under daily use. Lifespan varies with exposure to humidity, direct sunlight and frequency of wear. Crocodile leather generally outlasts ordinary calf due to its denser fibre structure. We recommend rotating with a second strap to extend the life of both, particularly during summer months.
