Frequently asked questions

What is the lug width of the Rolex Day-Date 36 reference 118348-0098?

The lug width of the Rolex Day-Date 36 118348-0098 is 20 millimetres. This measurement is taken between the two holes intended for the spring bar posts on the case. With this specific dimension, any compatible aftermarket strap may be mounted, from leather to rubber, fabric to metal.

What is the best strap material for the Day-Date 36 in yellow gold?

For the Rolex Day-Date 36 in yellow gold, alligator leather represents the classical choice par excellence, as its natural texture dialogues magnificently with the warmth of gold. Alternatively, superior quality calf leather offers a more contemporary elegance, whilst shell cordovan combines formal sophistication with tactical durability and a golden patina that develops over time.

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

Changing the strap on a Rolex Day-Date 36 is accomplished by removing the spring bar posts at the case ends using an appropriate tool (strap remover or specialised tool). After the original bracelet or strap has been removed, the posts are inserted into the new 20mm strap, aligning them with the case holes. The operation requires precision to avoid scratching the case; it is advisable to consult a professional if you lack experience.

Is an aftermarket strap compatible with a Rolex Day-Date 36 118348-0098?

Yes, any strap with a 20mm lug width is completely compatible with the Rolex Day-Date 36 118348-0098. The structure of the Rolex lug allows the installation of alligator, calf, shell cordovan, rubber, NATO, or fabric straps without any modification. Milanostraps.it offers a comprehensive collection of 20mm straps suited to this model.

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

The durability of a leather strap depends on the quality of the tanning, daily use, and exposure to atmospheric agents. A premium-quality alligator or shell cordovan strap can last 3–5 years with regular maintenance. Vegetable tanning ages gracefully, developing a patina that increases aesthetic value over time. With proper care, the investment in a premium strap pays dividends in longevity and evolutionary beauty.
