Strap for Rolex Yacht-Master 116621

The lug width of the Yacht-Master 116621 is 20 millimetres. This measurement represents the distance between the two spring bars on the case and is essential for selecting a compatible strap. To measure accurately, place a calliper between the two metal bars at the widest point of the lug seat: the result should be between 19.5 and 20.5 millimetres to ensure a perfect fit without forcing.

The ideal material depends on personal use and style. Alligator with vegetable tanning is the most elegant choice and dialogues perfectly with the Everose gold and two-tone steel: the deep grain and patina over time enhance the tactile value. Vegetable-tanned calf offers sobriety and an appealing patina development. Shell cordovan is the choice for those desiring natural water resistance and unique texture. For summer or casual use, NATO or FKM rubber ensures practicality whilst maintaining the model's sporty spirit.

To change the strap, remove the two spring bars from the case using a spring bar tool: a small metal lever specifically designed for this operation. Insert the tip of the tool into the lateral slots of the bar, press gently downward to release the pin, and the strap will come free. Repeat on the opposite side. To fit the new strap, insert the spring bars into the lug holes following the opposite direction. The operation requires care to avoid scratching the case: we recommend having it performed by an experienced watchmaker if you are not familiar with watch manipulation.

Yes, any strap with a 20-millimetre lug width is theoretically compatible with the Yacht-Master 116621. However, aesthetic compatibility is equally important: the two-tone steel-Everose gold case requires a choice of leather and colour that dialogues with this peculiarity. A cognac or black alligator, vegetable-tanned calf, or shell cordovan offer stylistic coherence with the character of the watch. Avoid very thick straps or ornate detailing that would overburden the elegant profile of the case.

The durability of a leather strap depends on the quality of the tanning, the type of leather, and the usage pattern. A strap in alligator or calf with vegetable tanning, worn regularly but not daily, can last 3–5 years before showing signs of structural wear (provided the lugs remain intact). Shell cordovan, due to its naturally water-resistant structure, is more durable and can exceed 5 years. Periodic cleaning with a soft damp cloth and occasional air exposure (avoiding direct sunlight) extend the lifespan. Standard warranty on manufacturing defects is 18 months.
