Strap for Heritage Black Bay 32 Stainless Steel / Blue / Strap

The lug width of the Tudor Black Bay One 79580-0004 is 20mm. This dimension reflects the historic construction standards of professional wristwatches from the 1950s. To measure correctly, use a digital calliper positioned perpendicularly between the two spring bar locations on the case lugs. MilanoStraps offers native 20mm straps and personalised adaptations upon request.

The ideal choice depends on intended use and personal aesthetics. Genuine alligator in vegetable tanning ensures evolving patina and tactile dialogue with the brushed case. Shell cordovan offers fibrous compactness and progressive natural lustre. Grained calf provides contemporary elegance with lower investment. Cotton vegetable-tanned NATO straps reference the Black Bay's military heritage. FKM rubber (Viton) represents the technical solution for frequent aquatic environments. We recommend consultation with Casati Milano atelier for personalised selection.

Strap replacement requires extraction of the primary pins (spring bars) using a dedicated two-pronged tool. Position the tool in the lateral groove of the pin and press downward until the metal lug releases from the tube. Remove the old strap, insert the new one into the groove, then reinsert the pin until the retention mechanism engages. Avoid excessive force to prevent damage to the delicate pins. MilanoStraps provides detailed instructions with every strap purchase.

All straps featuring a standard 20mm lug width are compatible with the 79580-0004. MilanoStraps offers a curated selection of artisanal straps in alligator, shell cordovan, calf, and technical textiles, with personalisation options in colour, initials, and stitching thread. Casati Milano atelier additionally crafts bespoke straps, permitting personal leather selection and ergonomic adjustments tailored to the wearer's wrist.

Leather strap longevity depends on material type and usage patterns. Alligator and shell cordovan in vegetable tanning maintain structural elasticity for 4–6 years of daily wear, evolving aesthetically throughout. Grained calf exhibits comparable durability. Vegetable tanning ensures reduced initial rigidity and diminished cracking tendency. Excessive moisture and prolonged dry heat reduce lifespan. MilanoStraps provides an 18-month warranty on all artisanal straps and recommends periodic maintenance with leather-specific care products.
