Frequently asked questions
What is the exact lug width of the Rolex Day-Date 36 118346-0044?
The lug width of the Rolex Day-Date 36 118346-0044 is 20 millimetres. This measurement is determined by the space between the lateral extremities of the case and represents the historical standard for Rolex's Day-Date segment. When purchasing an aftermarket strap, ensure it is compatible with 20mm lugs.
Which strap material is most suitable for a platinum Rolex Day-Date 36?
For a platinum Day-Date 36, satin-finished alligator leather or fine-grained calf leather are the most versatile choices: platinum's neutral tonality requires a strap that does not compete visually. If you prefer a sports-oriented solution, silk NATO, FKM rubber, or shell cordovan offer compelling contrasts. Selection depends on usage: formal occasions demand fine leather, daily wear permits greater material freedom.
How do you change the strap on a Rolex Day-Date 36 118346-0044?
Strap replacement requires releasing the lug pins using a specialised tool or dedicated remover. The procedure is straightforward: position the watch on a soft support, locate the small hole on the lug shoulder, insert the removal tool, and apply gentle downward pressure to extract the pin. Once removed, the strap will slide away. For installation, align the new strap's attachment holes and reinsert the pin until it locks securely.
Is an aftermarket 20mm strap genuinely compatible with the Rolex Day-Date 36?
Yes, provided it is constructed for 20mm lugs. The critical factor is that the strap features the same attachment holes at a 20mm distance. Italian artisan straps, crafted to specification, guarantee complete compatibility with your 118346-0044. We recommend verifying technical specifications before purchase, particularly if sourcing from manufacturers who do not explicitly communicate lug width.
How long does a leather strap last on a Rolex Day-Date 36 with daily wear?
A high-quality leather strap, realised in noble materials such as alligator or calf leather, typically lasts between 3 and 5 years with daily use and ordinary maintenance. Longevity depends on exposure to moisture, perspiration, and UV radiation. Vegetable-tanned leathers develop natural patina and age elegantly, whilst industrially-tanned leathers tend to deteriorate more rapidly. With Casati Milano, you receive an 18-month warranty covering manufacturing defects during the initial wear cycles.
