Frequently asked questions

What is the lug width of the Rolex Day-Date 36 reference 128235-0089?

The Rolex Day-Date 36 128235-0089 features a lug width of 20mm. This measurement is taken between the inner edges of the lugs on the 18ct rose gold case and is compatible with any standard 20mm aftermarket strap.

What is the best strap for the Rolex Day-Date 36 128235-0089?

For the Day-Date 36 128235-0089 in rose gold with a Sundust dial, a Horn-Back alligator strap in vegetable-tanned leather in Tabac, Cognac or Mahogany tones offers the most aesthetically coherent match. Shell cordovan develops an organic patina over time that complements the warm hues of rose gold. For everyday or sport use, a vulcanised rubber strap provides durability and comfort without compromise.

How do I change the strap on a Rolex Day-Date 36?

To remove the original bracelet from the Day-Date 36, use a 1.8mm springbar tool. The spring bars are located within the case lugs. Insert the tool tip into the side slot of the spring bar, compress it inward and slide the strap free. Exercise care to avoid scratching the rose gold lugs. Professional assistance from a qualified watchmaker or specialist atelier is recommended.

Is there an aftermarket strap compatible with the Rolex Day-Date 36 128235-0089?

Yes. Any aftermarket strap with a 20mm attachment and standard spring bars is technically compatible with the Day-Date 36 128235-0089. Milanostraps.it offers a curated selection of handcrafted straps in alligator, calf, shell cordovan and rubber, with straight or curved ends calibrated to fit the Day-Date lugs without modification. A rose gold deployant clasp is available on request to maintain visual consistency with the case.

How long does a leather strap last on a Rolex Day-Date 36?

The lifespan of a leather strap depends on the quality of the hide and frequency of use. A high-grade vegetable-tanned alligator strap, with daily wear and proper maintenance (regular cleaning, conditioning cream, rotation with other straps), retains its structural and aesthetic integrity for 3 to 5 years. Shell cordovan, due to its dense fibre structure, may exceed 5 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
