Frequently asked questions
What is the exact lug width of the Rolex Yacht-Master 226658-0001?
The Rolex Yacht-Master 226658-0001 has a lug width of 20mm. This measurement represents the internal distance between the two lugs of the case, measured orthogonally. Any compatible strap must be certified for this specific width to ensure secure anchoring and zero lateral play.
Which material is best suited for a strap on this yellow gold Yacht-Master?
For a Yacht-Master 226658-0001 in 18-carat yellow gold, alligator is the most refined choice: its natural grain structure captures light and harmonises perfectly with the warmth of the metal. If you engage in active sailing, shell cordovan offers superior resistance to saltwater and develops a unique patina over time. For daily wear, dark brown calf leather or vulcanised rubber are practical and durable alternatives.
How do you change the strap on the Rolex Yacht-Master 226658-0001?
The Yacht-Master 226658 uses straight pins measuring 20mm, which are extracted by pushing laterally with a small dedicated tool (spring bar tool). Position the watch on a stable surface, gently hold the strap from beneath the lugs, push the pin toward the opposite side until the spring retracts, and pull the pin out. Repeat for the second pin. The reverse operation follows the same principle: insert the new pin, align the holes, and allow the spring to snap into position.
Is an aftermarket strap compatible with the Rolex Yacht-Master 226658-0001?
Yes, provided the strap is specifically manufactured for a 20mm lug width. Bespoke artisanal straps offer maximum compatibility and allow you to personalise finishing, material, and colour to your preference. Avoid generic straps from unknown brands: the quality of stitching and material is crucial for preserving the watch's value.
How long does a leather strap last on this model?
Durability depends on material and usage. An alligator or shell cordovan strap, crafted with vegetable tanning, typically lasts 4–5 years with daily wear and regular maintenance (cleaning with a damp cloth, quick drying after water contact). A calf leather strap lasts 2–3 years. Vulcanised rubber is nearly indestructible, exceeding 10 years. An 18-month warranty on manufacturing defects provides additional protection against substandard materials.
