Day-Date 36 118346-0057— lug 20mm

The Rolex Day-Date 36 reference 118346-0057 features a lug width of 20mm. This measurement is critical when purchasing aftermarket straps: even minimal measurement errors result in incompatibility. We recommend verifying the exact distance between the case lugs using a digital calliper.

The platinum Day-Date 36 118346-0057 pairs naturally with alligator straps in cognac, calf leather in tobacco dark, or shell cordovan in deep black. For formal elegance, vegetable-tanned leather with a platinum deployante represents the supreme choice. For daily wear, light chestnut calf maintains versatility between formal and casual contexts.

Strap replacement requires removal of the spring bars using a dedicated Spring Bar Tool. Position the screwdriver in the lateral slot of the spring bar, lift gently and the strap disengages from the case lugs. Insert the new strap—the width must correspond exactly to the prescribed 20mm. Avoid excessive pressure: the platinum case, whilst robust, merits controlled movements.

Yes, any strap with 20mm lug width is compatible with the Day-Date 36 118346-0057, provided the width is measured with precision. Casati Milano artisanal straps are crafted to original Rolex specifications and guarantee total compatibility. Always verify that the leather does not protrude laterally beyond the case—the fit must be invisible.

A quality, vegetable-tanned leather strap lasts between 3 and 5 years of daily wear. Variability depends on solar exposure, ambient humidity and cleaning frequency. Shell cordovan and vegetable-tanned leather develop natural patina rather than wear: they age nobly. Casati Milano offers an 18-month warranty on manufacturing defects; periodic maintenance with specialist balm extends durability.
