Strap for Heritage Black Bay Bronze / Brown / Leather

The Tudor Black Bay Bronze 79250BM-0005 is fitted with a lug width of 23 millimetres. This non-standard measurement represents Tudor's official construction specification for this model and must be observed when selecting any aftermarket strap. To verify the lug width of your timepiece, measure the distance between the inner axes of the two metal lugs (spring bar attachment points) using a ruler or digital calliper.

The choice depends on intended use and aesthetic preference. A naturally tanned alligator strap with vegetable tanning complements the organic patina of the bronze case, with parallel ageing characteristics. A vegetable-tanned calf strap in cognac or deep chestnut maintains chromatic coherence with the patinated case. For frequent underwater use, a black or grey FKM rubber strap offers practicality and salt-water resistance. Heavy canvas NATO straps preserve the model's historical military character.

Strap replacement is accomplished by extracting the metal spring bar pins. Use a spring bar tool or small flathead screwdriver: insert the tool into the gap between case and strap at the pin location, and press inward to release the internal spring mechanism. Once the pin is removed, the strap slides free. Reverse the procedure with the new strap, ensuring the pins seat correctly into the case lugs.

Yes, this is both possible and recommended. The Black Bay Bronze accepts any strap constructed to the 23mm lug width specification, which is the determining technical parameter. Quality aftermarket straps enable aesthetic personalisation consistent with the watch, respecting materials (alligator, calf, rubber) and the ageing processes the bronze case is already undergoing. Milano Straps offers a selection of 23mm options ready for dispatch.

Leather strap longevity depends on construction quality, tanning method, and usage patterns. A well-constructed alligator or vegetable-tanned calf strap maintains functionality and aesthetics for 3-5 years of daily wear, with potential for colour restoration through professional cleaning. Frequent exposure to salt water or harsh detergents reduces lifespan. An FKM rubber strap lasts considerably longer, 7-10 years, without perceptible colour degradation. Casati Milano provides an 18-month warranty on each handcrafted strap.
