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

The lug width of the Tudor Black Bay One 79580-0008 is 20mm. This measurement is critical for aftermarket strap compatibility and should be measured as the distance between the two metal spring bars that pass through the case lugs.

Alligator is the most natural choice for this model, thanks to its geometrically tight grain pattern that pairs perfectly with the compact 32mm case. Vegetable-tanned calf leather is also an excellent alternative, particularly for those seeking a patina that evolves naturally over time.

Remove the strap using a spring bar tool to extract the metal pins from the lugs. Place the watch on a soft surface, insert the tool into the gap between the case and strap, compress the spring mechanism, and slide the pin out. Repeat on the other side, then install the new strap by reversing the procedure.

Yes, any strap with a 20mm lug width is compatible with the 79580-0008. Custom-crafted straps from Milano Straps guarantee full compatibility whilst offering personalisation options in leather type, colour, and stitching thread.

Leather strap durability varies depending on material (alligator, calf, shell cordovan) and usage patterns. A quality artisanal strap typically provides 3–5 years of daily wear. Alligator tends to last longer due to grain density, whilst calf evolves aesthetically but remains functional for comparable periods. Casati Milano guarantees their straps for 18 months.
