Frequently asked questions

What is the lug width of the Rolex Day-Date 36 118235f-0024?

The lug width of the Rolex Day-Date 36 118235f-0024 is 20 mm. This is the distance between the two articulation pins of the case. This dimension is intermediate compared to other Rolex models: greater than the 19 mm of the classic Datejust, and smaller than the 21 mm of the Submariner. It is crucial to measure correctly to ensure the strap inserts without force.

What is the best strap for the Rolex Day-Date 36 in rose gold?

For the 118235f-0024 in 18-carat rose gold, we recommend French alligator (havana or dark tobacco tone), Italian calf leather vegetable-tanned (medium brown tonality), or Japanese shell cordovan for those seeking elasticity and durability. We advise against NATO straps, as their industrial robustness contrasts with the whispered elegance of the rose gold case. A solid rose gold deployante clasp amplifies chromatic harmony.

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

The operation requires a specific tool: a spring bar tool with two pointed ends. Position the watch on a clean cloth, gently press one end of the tool under the articulation pin until compressing the internal spring, extract the pin from the case hole. Repeat on the other side. Insert the new pins from the replacement strap in the same manner, ensuring they are properly aligned. Never use screwdrivers or sharp tools: the risk of scratching the rose gold case is significant.

Can I use aftermarket-compatible straps with my 118235f-0024?

Yes, 20 mm aftermarket straps are compatible with the Rolex Day-Date 36 118235f-0024, provided they respect the lug width precisely. However, we recommend specialised artisans who understand the constructive constraints of this dimension and who use noble leathers (genuine alligator, vegetable-tanned calf, shell cordovan). Casati Milano, for instance, offers a bespoke service by appointment at their Milan atelier.

How long does a leather strap typically last on this watch?

The lifespan of a leather strap depends on material quality, frequency of wear, and maintenance. Genuine alligator or superior-grade shell cordovan, worn daily, maintain structural integrity for 4-6 years. Vegetable-tanned calf leather exhibits similar durability, though patina evolves more rapidly. Extended exposure to moisture, heat, and UV rays accelerates degradation. To preserve your strap, avoid direct water contact, dry with a soft cloth if wet, and store in a climate-controlled environment.

The next step

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

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
