The Day-Date II 218235-0035, seen from the bench

The Day-Date II represents the evolution of the classic Day-Date with an enlarged 41mm case. It is equipped with the automatic calibre 3156 with chronometer certification and double indication of date and day of the week. The case is made of rose gold with 21mm lugs.

Frequently asked questions

What is the exact lug width of the Rolex Day-Date II 218235-0035?

The lug width of the Day-Date II 218235-0035 is 21 mm, measured from inner edge to inner edge between the two lugs. This measurement is specific to the 41 mm version and is not compatible with 20 mm or 22 mm lugs. To verify accurately, use a digital calliper positioned between the attachment points, or consult the Rolex documentation accompanying the international warranty.

Which strap material is recommended for the Day-Date II 218235-0035 in rose gold?

For the Day-Date II in rose gold, alligator is the natural choice and most harmonious. The fine grain of the leather and the patina it develops over time mirror the chromatic evolution of rose gold. Quality alternatives include shell cordovan, which offers durability and visible patina, and vegetable-tanned leather for artisanal authenticity. Avoid synthetic or NATO fabrics, which are incompatible with the watch's stylistic dignity.

How do you change the strap on the Rolex Day-Date II 218235-0035?

Changing the strap requires a specific tool to remove the pins or lugs securing the strap to the case. Since the rose gold case is solid, it is advisable to entrust the operation to an experienced or Rolex-authorised technician to avoid scratching the case. The procedure is straightforward: gently release the pins and slide out the old strap, then insert the new one, aligning it perfectly with the lugs.

Can an aftermarket compatible strap be used on this Day-Date II?

Yes, it is possible to use quality aftermarket straps, provided they strictly adhere to the 21 mm lug width and are constructed from noble materials (alligator, shell cordovan, vegetable-tanned leather). Casati Milano straps for this size are 100% compatible and available both online and by appointment at the Milan atelier, with an 18-month guarantee against manufacturing defects.

What is the average lifespan of a leather strap on this model?

A fine leather strap (alligator, shell cordovan, vegetable-tanned) has an average lifespan of 3–5 years when worn daily, with variation depending on climate, humidity, and frequency of use. Vegetable-tanned leather ages more slowly and develops patina, whilst alligator maintains its structure longer. Replacement depends on physical wear and personal aesthetic preference; the patina itself may warrant keeping rather than changing.

The next step

The right strap isn't chosen. It is built, together.
