Day-Date 36 118348-0151— lug 20mm

The lug width of the Rolex Day-Date 36 118348-0151 is 20 millimetres. This measurement refers to the internal width of the lugs where the strap attaches to the case. It is essential to verify this measurement before purchasing a replacement strap to ensure proper compatibility.

For the Day-Date 36 in yellow gold, alligator leather represents the classical and most authoritative choice. Cognac brown or deep black create natural chromatic harmony with the gold. Burgundy shell cordovan offers a sophisticated alternative, whilst vegetable-tanned calf leather provides a more contemporary character. Vulcanised rubber in navy blue or dark grey allows daily versatility without aesthetic compromise.

Remove the strap on the Day-Date 36 118348-0151 by using a spring bar tool to release the lugs. Insert the tool into the cavity between the case and strap, applying light pressure to loosen the spring bar. Once the spring bar is extracted, the strap separates easily. To install a new strap, position the spring bar in both lug slots with precision, then snap the opposite end into its slot until you hear an audible click.

Yes, any strap with a 20-millimetre lug width is compatible with the Day-Date 36 118348-0151, including premium aftermarket straps. The essential requirement is to verify that the lug width measurement is precisely 20mm. Casati Milano straps, hand-crafted at the Milanese atelier, guarantee construction quality and precision matching Rolex standards, with the added benefit of complete personalisation.

A high-quality leather strap, properly maintained, typically lasts 3 to 5 years with daily use. Longevity depends on leather type (cordovan and alligator outlast calf leather), tanning method (vegetable tanning is more durable than chrome tanning), and maintenance habits. By avoiding prolonged water and perspiration exposure, occasionally applying conditioner, and rotating between multiple straps, you can extend lifespan to 5-7 years. Casati Milano's 18-month warranty covers all manufacturing defects.

Yes, vulcanised rubber is fully compatible with the Day-Date 36 118348-0151.

Colours such as navy blue, dark grey, or black preserve the watch's elegance whilst conferring a more contemporary and sporty aesthetic, ideal for intensive daily use.
