Strap for Heritage Black Bay 32 Stainless Steel / Silver / Bracelet

The lug width of the Tudor Black Bay One 79580-0007 is 20 millimetres. This dimension, proportioned to the 32 mm case diameter, is compatible with a wide range of artisanal straps available in this standard width. To verify correct measurement, use a digital calliper positioned between the two internal attachment pins of the case.

The ideal strap depends on intended usage. For a refined look, alligator leather in brown with steel deployante is recommended. For a minimalist, urban aesthetic, black vegetable-tanned calf is perfect. If you prefer sporty versatility, a slate grey NATO strap or FKM rubber strap guarantee comfort and practicality. The range of customisable 20mm straps allows you to adapt the timepiece to your personal style.

Strap replacement requires simple tools: a spring bar tool and a well-lit work surface. Position the watch with the case facing up, gently insert the spring bar tool between the lug and strap, pressing downward to compress the internal spring. Once the pin is freed, remove the old strap. To install the new one, align the holes with the pins, use the tool to compress the spring, and secure the strap at both ends.

All straps with 20mm lug width are compatible with the Tudor Black Bay One 79580-0007. The offering includes alligator leather, shell cordovan, vegetable-tanned calf, NATO fabrics, elastomers and FKM rubbers. Choose based on material, colour and preferred style: compatibility is guaranteed by the standardised 20 millimetre lug width.

The lifespan of a leather strap depends on material quality and frequency of use. A high-quality leather such as alligator or shell cordovan maintains structural integrity for 5–10 years with regular maintenance (gentle cleaning and bi-annual conditioning). Vegetable-tanned leathers develop a natural patina that enhances aesthetics over time. Excessive moisture and prolonged sun exposure accelerate ageing. The 18-month warranty offered by Casati Milano on bespoke straps testifies to construction quality and expected durability.
