Frequently asked questions
What is the exact lug width of the Rolex Day-Date 36 118238-0200?
The Rolex Day-Date 36 reference 118238-0200 features a lug width of precisely 20 millimetres. This specification is unique to the Day-Date 36 models of this generation and must be measured perpendicularly across the case lugs. A compatible strap must have exactly 20 mm width at the attachment points.
Which type of strap is most recommended for the Day-Date 36 118238-0200?
For the Day-Date 36 in yellow gold (reference 118238-0200), natural alligator is the most traditional and refined choice, particularly in black or cognac tones. Shell cordovan represents the pinnacle for longevity and patina development over time. Vegetable-tanned calfskin offers practicality and structure while maintaining formal elegance. All these materials enhance the richness of the gold case without competing visually.
How do you change the strap on a Day-Date 36 118238-0200?
Changing the strap on a Day-Date 36 118238-0200 requires a spring bar tool to extract the metal pins from the case lugs.

What is the average lifespan of a leather strap for the Day-Date 36 118238-0200?
A high-quality leather strap, such as those crafted from natural alligator or shell cordovan, typically lasts 3-5 years with daily use and proper maintenance.
