Strap for Day-Date 36 Everose / Strap / Pink Computer

The lug width of the Rolex Day-Date 36 118135-0081 is 20 millimetres. This measurement is standard for Rolex classical models of medium diameter and determines compatibility with all aftermarket straps. To measure the lug width, insert a calliper between the two metal pins (spring bars) protruding from the case: the construction tolerance is between 19.8 and 20.2 millimetres to guarantee perfect fit without play or stress on the lug slots.

For a rose gold 118135-0081, dark brown alligator and shell cordovan in burgundy tones offer the finest aesthetic and structural balance. Alligator enhances the reflectivity of the precious case through parallelogram grains; shell cordovan patinates naturally towards tonalities complementary to rose gold. Vegetable-tanned calf in cognac offers a versatile alternative for formal settings, whilst vulcanised black rubber enables contemporary usability whilst maintaining case dignity.

To change the strap on the 118135-0081, you must first remove the integrated President bracelet. Use a spring bar removal tool and gently push the pins towards the centre of the case to release the terminal links. Insert the new spring bars into the case lugs, then snap the strap into position. Verify that the strap width is correct (20mm) and that the spring bars are fully seated. If inexperienced, consult a professional watchmaker to avoid case damage.

Yes, any strap with a 20-millimetre lug width is compatible with the 118135-0081. Aftermarket straps in alligator, shell cordovan, vegetable-tanned leather, velvet and rubber are entirely suitable for this case. Compatibility is guaranteed by lug width; however, select suppliers who employ watchmaking-grade spring bars to ensure secure and durable fastening. Casati Milano provides bespoke 20mm straps with an 18-month warranty against manufacturing defects.

The lifespan of a leather strap on the 118135-0081 depends on material, frequency of use and climatic conditions. Shell cordovan or alligator with natural tanning resists 3–5 years of daily wear before replacement; vegetable-tanned calf lasts 2–4 years; lower-grade vegetable leather, 1–3 years. Exposure to moisture, heat and ultraviolet radiation accelerates ageing. Casati Milano straps, crafted with Europe's finest leathers, are engineered for maximum longevity and develop elegant patina over time, often improving aesthetically during the opening months of wear.
