Frequently asked questions

What is the lug width of the Rolex Day-Date 36 118205f-0062?

The lug width of the Rolex Day-Date 36 118205f-0062 is 20 millimetres. This dimension requires straps specifically constructed for this width and are not compatible with models featuring 18mm or 22mm lugs. Precision in measurement is essential to ensure the strap adheres perfectly to the case lugs without lateral play.

Which strap material is most suitable for the Day-Date 36 in rose gold?

For a Day-Date 36 in 18-carat rose gold, alligator represents the most coherent aesthetic choice: its natural texture and patina development over time align perfectly with the ageing of rose gold. Alternatively, vegetable-tanned calf offers a more restrained aesthetic and a richer tactile perception. Shell Cordovan is reserved for those seeking even greater exclusivity and a surface that assumes characteristic patina with use.

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

The Day-Date 36 strap is secured using spring bars housed vertically in the case lugs. To remove it, you must use an appropriate tool—a thin lever for spring bars—to apply controlled pressure on the spring and release the strap. The operation requires delicacy to avoid scratching the case: it is advisable to rely on a professional watchmaker or follow the technical instructions provided by Rolex. Should you order a personalised strap from our atelier, detailed fitting instructions will be provided.

Is an aftermarket strap compatible with the Day-Date 36 118205f-0062?

Yes, any strap constructed for 20mm lugs is compatible with the Day-Date 36 118205f-0062, regardless of manufacturer. Compatibility depends exclusively on lug width, not the watch brand. However, to ensure aesthetic coherence, it is essential that the strap is crafted with care and refined finishing, exactly as our models available online.

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

The lifespan of a leather strap depends on the material, daily use and environmental conditions. A quality alligator strap can last 3-5 years under moderate daily use. Naturally tanned leather ages visibly, developing patina and tonal variations. Shell Cordovan is renowned for superior longevity (5-7 years) due to its natural density. With proper maintenance—periodic cleaning with a damp cloth and occasional conditioning—the strap's useful life extends significantly.
