Day-Date 36 118348-0152— lug 20mm

The Rolex Day-Date 36 reference 118348-0152 features a lug width of 20 mm, measured at the base of the case at the strap attachment point. This is the standard measurement for the entire Day-Date 36 family and requires straps with precisely machined attachment horns to prevent lateral play against the solid yellow gold lugs.

For the Day-Date 36 118348-0152 in yellow gold, an alligator strap in vegetable-tanned leather is the most coherent choice with the watch's formal identity. The large-scale grain texture complements the polished gold surface without competing with it. Shell cordovan is the preferred alternative for those who appreciate a patina that develops with wear, whilst vulcanised rubber suits more active use.

Replacing the strap on a Day-Date 36 requires removing the springbars from the lugs using a dedicated spring bar tool with a forked tip. As the lugs are crafted in solid gold, they are susceptible to scratching: it is advisable to protect the case with surgical tape during the operation and to use quality springbars, preferably in stainless steel with a 1.8 mm diameter, compatible with the 20 mm Oyster lugs.

Yes, the aftermarket offers straps compatible with the 20 mm lug width of the Day-Date 36 118348-0152. Milanostraps.it provides a selection of handcrafted straps in leather, rubber and fabric made to measure for this format. It is important to verify that the attachment horn profile suits the integrated lugs of the Day-Date to ensure correct fit and absence of lateral movement.

The lifespan of a leather strap depends on material quality and frequency of use. A high-quality vegetable-tanned alligator strap, with regular use and proper care — kept away from water, excessive perspiration and heat sources — will maintain its aesthetic and structural characteristics for three to five years. Casati Milano offers an 18-month guarantee against manufacturing defects on all handcrafted straps.
