Frequently asked questions

What is the lug width of the Rolex Yacht-Master 168623-0018?

The Rolex Yacht-Master 168623-0018 has a lug width of 17mm. This specific measurement requires straps produced to exact tolerances to ensure a correct fit with no lateral play between the spring bar and the lug walls.

What is the best strap for the Rolex Yacht-Master 168623-0018?

For the Yacht-Master 168623-0018, featuring a mother-of-pearl dial and 18k yellow gold inserts, a vegetable-tanned alligator strap in cognac or tobacco tones provides the best balance between material refinement and aesthetic coherence. A vulcanised rubber strap is the preferred choice for nautical use.

How do you change the strap on a Rolex Yacht-Master 168623-0018?

To replace the strap on the Yacht-Master 168623-0018, use a fine-tipped spring bar tool inserted into the side hole of the lug to compress the spring bar. Work on a soft surface to avoid scratching the steel case or gold inserts. If in doubt, a watchmaker or the Casati Milano service can perform the swap safely.

Are there aftermarket straps compatible with the Rolex Yacht-Master 168623-0018?

Yes. Aftermarket straps made to a 17mm lug width are fully compatible with the Rolex Yacht-Master 168623-0018. Milano Straps offers a curated selection of handcrafted straps in various leathers and materials, cut to the precise lug width required by this reference.

How long does a leather strap last on a Rolex Yacht-Master 168623-0018?

The longevity of a leather strap depends on material quality, tanning method, and usage. A vegetable-tanned alligator strap, properly conditioned and rotated with other straps, can last between 5 and 10 years while developing a distinguished patina. Prolonged exposure to salt water and perspiration significantly shortens leather lifespan; rubber or NATO straps are recommended for marine use.
