Day-Date 36 118208-0106— lug 20mm

The Rolex Day-Date 36 reference 118208-0106 features a lug width of 20 millimetres, which is the distance between the two lugs on the case where the strap attaches. This standard is characteristic of presidential models in 36 millimetres and can be easily measured by placing a ruler from the top of one lug to the other.

For the Day-Date 36 in yellow gold, alligator represents the most noble and historically accurate choice: the natural texture of the scales contrasts elegantly with the lustre of the gold. Shell cordovan is a sophisticated alternative for those desiring intense luminosity and characteristic ageing. Vegetable-tanned calf leather is the most versatile solution, suitable for both formal and casual contexts.

The strap is attached to the case via spring bars positioned at the two lugs. Using a dedicated tool (spring bar tool), press the bar to release one end of the strap, slide off the old strap, then insert the new one by aligning the holes with the bar and releasing. This operation can be performed at home or by a professional jeweller.

Yes, any strap with a 20 millimetre lug width and standard spring bars is compatible with the Day-Date 36 118208-0106. Premium artisanal straps, such as those available on milanostraps.it, guarantee aesthetics and durability comparable to the original Rolex, often with greater customisation options.

Longevity depends on leather quality and use frequency. An alligator or shell cordovan strap with vegetable tanning typically lasts 5-10 years with daily wear, developing a desirable patina. Quality artisanal calf leather resists 3-7 years of use. Regular maintenance (gentle cleaning, proper drying, occasionally a natural conditioner) significantly extends the strap's lifespan.
