Frequently asked questions

What is the lug width of the Rolex Yacht-Master 116621-0001?

The Rolex Yacht-Master 116621-0001 is equipped with a lug width of exactly 20 millimetres. This measurement is standard for the model and determines compatibility with any aftermarket strap. Always verify the physical width of the lug space on your case before ordering a replacement strap.

Which strap material is recommended for the Yacht-Master 116621-0001?

Rich brown alligator leather with vegetable tanning offers maximum aesthetic harmony: its natural patina dialogues with the Rolesium dial and does not compete with the rose gold/steel bi-metallicity. For frequent marine use, pressed rubber or technical NATO nylon provides secure grip in salt-water environments. We do not recommend shell cordovan due to its inherent rigidity and poor moisture resistance.

How do you change the strap on a Rolex Yacht-Master 116621-0001?

Strap replacement requires a spring bar tool. Remove the old strap by starting on one side of the case, align the new pins with the lug slots, insert them under controlled pressure until the locking click engages. We recommend consulting a certified watchmaker if you lack experience with horology tools.

Is an aftermarket strap compatible with the Rolex Yacht-Master 116621-0001?

Yes, provided the strap features a 20-millimetre lug width. Milanostraps.it offers handcrafted leather and rubber straps dimensioned specifically for this measurement. Aftermarket strap quality directly influences durability and overall watch aesthetics; we recommend materials such as alligator, vegetable-tanned calf, or technical NATO nylon.

How long does a leather strap last on the Rolex Yacht-Master 116621-0001?

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 2–4 years with daily wear and routine maintenance. Longevity depends on environmental conditions (humidity, UV exposure), frequency of wear, and leather care practices. A well-maintained strap can last 5–6 years. Casati Milano provides an 18-month warranty against manufacturing defects.
