Strap for Yacht-Master 2 Stainless Steel

The lug width of the Rolex Yacht-Master 116680-0002 is 21mm, measured from the inside of the left lug to the inside of the right lug. This width is specific to this model and requires a strap with tight tolerances to ensure perfect fit without lateral play. Measurement is performed using a digital calliper, positioning the tips against the interior of the case lugs.

For the brushed steel finish of the 116680-0002, Burmese alligator with medium grain is the optimal choice: the contrast between the soft leather texture and the hard case geometry creates visual harmony. Alternatively, Italian shell cordovan offers structural rigidity and visible ageing with natural patina. For actual nautical use, Cordura nylon NATO or FKM rubber ensures resistance to salt water.

Changing the strap on the 116680-0002 requires a spring bar tool. Position the watch with the lug facing upward, insert the flat tip of the tool under the internal spring bar and push downward with uniform pressure until it releases. Repeat on the other side. Insert the new strap by engaging the bar in the case lugs until it clicks into place. A strap with a deployant buckle in 904L steel allows tool-free rapid changes.

Yes, an aftermarket strap with 21mm lug width is fully compatible with the 116680-0002. It is essential to verify construction tolerance: Atelier Casati Milano manufactures straps with ±0.2mm tolerance, ensuring fit identical to the original Rolex strap. Avoid straps with loose tolerances (±0.5mm or greater), as they cause lateral play and instability during wrist rotation.

A quality leather strap (alligator, shell cordovan, calf) mounted on a 116680-0002 maintains optimal functionality for 3–5 years with daily use, provided regular maintenance (monthly cleaning with a damp cloth, immediate drying after moisture exposure). Occasional use extends lifespan to 7–10 years. The 904L steel deployant buckle reduces wear compared to the original Rolex strap, as it requires no additional perforation over time. Casati Milano guarantees 18 months against manufacturing defects.
