Strap for Heritage Black Bay 41 Blue / Bracelet

The Tudor Black Bay One 79540-0004 features a lug width of 22mm. This measurement represents the distance between the inner edges of both lugs and is essential for selecting compatible straps. The 22mm width allows for pairing with straps from various collections, from textured leather to technical fabrics, whilst maintaining precise fit and no play on the case.

For the 79540-0004, we recommend straps in dark brown alligator or vegetable-tanned calf leather. These materials create an extraordinary visual balance with the case's brushed finish and midnight blue dial. Alligator offers three-dimensional texture that captures light, whilst calf develops natural patina over time. Shell cordovan is equally excellent for those seeking structural compactness and controlled luminosity.

Strap replacement on the 79540-0004 is performed using a spring bar removal tool. Insert the tool into the small lateral hole of the lug to compress the internal spring, release the old strap, and position the new one. The operation requires care to avoid scratching the brushed case. For precise fitting, it is advisable to have the operation performed by a specialist atelier.

Absolutely yes. The 79540-0004, with its 22mm lug width, is completely compatible with quality aftermarket straps. What matters is selecting a manufacturer that guarantees precise constructive tolerances and uses durable materials. Artisanal straps in alligator, calf, or shell cordovan offer superior aesthetic versatility compared to original solutions, allowing personalisation according to individual taste.

The lifespan of a leather strap depends on tanning method, thickness, and wear patterns. A vegetable-tanned calf strap worn daily maintains structural integrity for 3-5 years. Alligator and shell cordovan, more resistant, can last 5-7 years. The natural patina that develops over time is an aesthetic advantage. Regular care—gentle cleaning and protection from extreme humidity—significantly extends the strap's useful life.
