Strap for Heritage Black Bay 41 S&G / Champagne / Bracelet

The lug width of the Tudor Black Bay One 79543-0002 is 22 millimetres. This measurement represents the distance between the two terminal rings of the case where the strap is attached. Precision is essential when measuring before purchasing a replacement strap to ensure perfect compatibility.

For the Black Bay One 79543-0002, we recommend alligator leather in dark mahogany tone or calf leather with vegetable tanning in cognac brown. Alligator amplifies the sophistication of the bicolour gold-steel design, whilst vegetable-tanned calf echoes the technical character of the bezel. Avoid straps in cool tones or vivid colours that would compromise the warm chromatic identity of the model.

To change the strap, obtain a dedicated spring bar tool that allows you to push the strap barrels inward and disengage the rings. Remove the old strap by pushing the barrel from beneath the lug, then insert the new strap by aligning the barrels into the lug spaces and ensuring they sit fully. Verify visually that the strap is secure before wearing the watch.

Yes, you can use aftermarket straps compatible with the 22mm lug width. Milano Straps offers a curated selection of straps in alligator, calf, shell cordovan and other materials specifically calibrated for this dimension. Ensure the strap respects the aesthetic proportions of the model—opt for premium leathers and chromatic tones coherent with the bicolour character of the timepiece.

The durability of a leather strap depends on usage intensity, tanning quality and climatic conditions. A high-quality artisanal alligator or calf strap, with regular maintenance (light cleaning and semi-annual conditioning), guarantees 5–8 years of aesthetic and functional performance. Milano Straps offers an 18-month warranty on all custom straps, and replacement is straightforward thanks to the 22mm lug width, which provides easy access to numerous replacement options.
