Strap for Rolex Yacht-Master 116655

The Rolex Yacht-Master 116655 features lug width (or lug holes) of 20mm. This measurement is essential for strap compatibility: aftermarket straps must be sized precisely to 20mm. Installing straps of different dimensions (18mm or 22mm) would require unsuitable adapters, compromising both aesthetics and functionality. The 20mm width results from Rolex's proportional design for a 40mm case and 11.5mm thickness.

The choice depends on usage and aesthetic preference. For nautical and dressy contexts, an alligator strap with vegetable tanning ensures breathability, predictable patina development, and tactile grip. For lightweight practicality, fine-grained calf leather with asymmetrical texture complements the minimalist dial geometry. In humid or summer environments, a tight NATO weave or technical rubber maintains the model's sporty character. Everose gold demands straps that do not compete chromatic­ally: dark browns, blacks, burgundy, and occasionally cognac are safe choices.

Strap replacement requires a spring bar tool. Position the watch on a flat surface, dial facing downward. Locate the spring bar tension mechanism inside the lower lug and press gently upward with the tool to disengage the tension, then slide the lug outward. Repeat for the upper lug. When installing the new strap, ensure the spring bars seat correctly in their fixtures with a firm click. Avoid excessive force during installation, as this may damage the lug or the new strap's attachment points.

Yes, provided the strap is dimensioned specifically for 20mm lugs and respects the case profile (maximum thickness at attachment point of 4.5–5mm). A handcrafted full-grain leather strap with a deployante clasp or simple buckle from a specialised atelier like Casati Milano causes no damage to the watch's value and enhances aesthetic expression through personalised colour and material choices. Verify that stitching is even and that the attachment point shows no puffing or irregularities, which could mar the lugs or case over time.

Durability depends on material type, tanning method, and intensity of use. An alligator strap with vegetable tanning, if regularly exposed to marine moisture, retains structural integrity for 2–3 years with proper care (gentle drying and periodic protective treatments). Fine-grained calf, in less humid environments, may last 3–4 years. NATO or technical rubber straps, being leather-free, can exceed 5 years without softening or decomposition. Casati Milano offers an 18-month warranty against manufacturing defects and crafts straps using techniques that foster a predictable, dignified patina development rather than degradation.
