Strap for Black Bay 41 Stainless Steel / Black - Diamond / Bracelet

The lug width (ansa) of the Tudor Black Bay One 79680-0004 is 22mm. This measurement is taken between the two lug holes where the spring bars insert. All examples of this model maintain this specification consistently.

The ideal strap depends on your intended use. For formal elegance, we recommend Nile crocodile or vegetable-tanned calf leather with a satin finish. For daily wear, shell-grain calf provides grip and develops natural patina over time. For water-related activities, vulcanised rubber or technical NATO fabric offer durability and resistance.

Use a spring bar tool to gently insert the flat tip into the slot alongside one lug hole. Press downward slightly to compress the internal spring and extract the old bar. Position the new bar and press it firmly into place, ensuring it is fully seated on both sides of the case.

All straps with a 22mm lug width are compatible. We recommend selecting watch-grade quality materials: genuine alligator, vegetable-tanned calf, shell cordovan, or certified vulcanised rubber. Always ensure the strap's buckle or deployante closure does not protrude excessively and risk scratching the case.

A high-quality leather strap typically lasts 3 to 5 years with moderate daily use. Factors such as humidity, prolonged sun exposure, and friction accelerate deterioration. Vegetable-tanned leather ages gracefully, developing character and patina. Vulcanised rubber straps are more durable, lasting 5 to 8 years, though their water resistance diminishes over time.
