Day-Date 36 118235f-0004— lug 20mm

The Rolex Day-Date 36 ref. 118235f-0004 has a lug width of 20mm. This measurement is taken at the narrowest point between the case lugs, where the strap or bracelet is attached. Always specify 20mm when ordering any aftermarket strap for this reference.

For the rose gold Day-Date 36, a ciré alligator strap in bordeaux or cognac offers the most authoritative pairing, with its large-grain texture complementing the warm tones of Everose gold. Box-calf black lacquered leather provides a sharp formal contrast. For casual or outdoor wear, a vulcanised rubber strap in brown maintains chromatic coherence with reduced risk of moisture damage.

Changing the strap on the Day-Date 36 requires a fine-tipped spring bar tool to remove the 20mm spring bars seated within the lugs. It is advisable to use a nylon-tipped or coated tool to avoid scratching the rose gold lug surfaces. The operation is fully reversible and does not compromise the case's water resistance.

Yes. Any strap with a 20mm attachment and curved ends to follow the profile of the Oyster lugs is compatible with the ref. 118235f-0004. Milanostraps.it offers a curated selection of handcrafted 20mm straps specifically proportioned for the Day-Date 36, available in alligator, calf leather, shell cordovan and other premium materials.

Lifespan depends on the leather chosen and frequency of wear. A quality handcrafted alligator strap with vegetable tanning and hand-finished edges typically lasts between two and four years with regular daily use. Calf leather develops patina more quickly. Exposure to perspiration, water and fragrances accelerates degradation; rotating straps and storing them away from direct light is strongly recommended.
