Strap for Heritage Black Bay 36 Stainless Steel / Black / Bracelet

The Tudor Black Bay One 79500-0007 features a lug width of 19 millimetres. This dimension is specific to this model and requires straps manufactured to this precise specification. To verify your lug width correctly, position a calliper in the narrowest zone between the lug ears, where the strap attaches to the case.

The Tudor Black Bay One 79500-0007 pairs ideally with alligator straps in black for formal occasions, or with vegetable-tanned calf leather for everyday versatility. Both materials reflect the functional sobriety of the watch. A high-tenacity polyamide NATO strap is the practical choice for sport contexts. Selection depends upon your lifestyle and predominant occasions of wear.

To change the strap on the Tudor Black Bay One 79500-0007, use a dual-ended springbar tool. Insert the flat end of the tool into the small access hole positioned on the lug shoulder, push outward to release the springbar pin from the previous hole, then extract the strap. Reverse the procedure to mount your new 19mm strap, ensuring the pin clicks firmly into position.

Yes, the Tudor Black Bay One 79500-0007 accepts any quality strap manufactured for a 19-millimetre lug width. Artisanal aftermarket straps offer greater personalisation than original equipment. Ensure the strap is constructed from noble materials (alligator, calf, technical rubber) and that the craftsmanship finishing is coherent with the watch's dignity.

The lifespan of a leather strap depends upon intensity of wear, climate, and material quality. A vegetable-tanned calf strap lasts approximately 3–5 years with daily wear, developing characteristic patina over time. An alligator strap, more resilient, may reach 5–7 years. Periodic maintenance—gentle cleaning, application of natural balms—significantly extends longevity. Casati Milano provides an 18-month warranty on all artisanal straps.
