Day-Date 36 118208-0134— lug 20mm

The Rolex Day-Date 36 reference 118208-0134 features a lug width of 20 millimetres. This measurement represents the distance between the two spring bars that attach the strap to the case. It is essential to verify this dimension before purchasing an aftermarket strap, as even minor variations (18 or 22 mm) would compromise fit and overall aesthetic compatibility.

For the 118208-0134 in yellow gold, French or Bangladeshi alligator represents the formal choice of excellence, thanks to its fine grain and regular texture that enhance the golden tonality. European calf in vegetable tanning offers a versatile, supple alternative suitable for alternating formal and daily wear. For summer months, shell cordovan in cognac or burgundy creates sophisticated colour pairings. Natural rubber remains a practical solution without aesthetic compromise.

The strap of the 118208-0134 is changed using a specialized tool (spring bar tool) to extract the fixing pins from the case. Position the watch with the lug side facing upwards, insert the tool tip into the pin slot and gently push downward until the pin compresses. Extract the pin and strap from the case, then insert the new strap and reinsert the pins. This operation requires care to avoid scratching the yellow gold case.

Yes, many artisanal strap makers produce 20mm aftermarket straps compatible with the 118208-0134. The key is selecting materials and finishes worthy of the yellow gold case and Rolex 3155 movement. Milano Straps offers bespoke straps crafted at the Casati Milano atelier, with the opportunity to follow production via WhatsApp and an 18-month warranty against manufacturing defects.

The lifespan of a leather strap depends on material quality, frequency of wear and climatic conditions. High-grade alligator typically lasts 2-3 years with daily wear, whilst calf might require replacement every 2-4 years. Shell cordovan, thanks to its density, can extend to 4 years. Exposure to humidity, direct sunlight and perspiration accelerates ageing. Casati Milano's bespoke straps include an 18-month warranty against manufacturing defects.
