Strap for Tudor Black Bay One 79540

The Tudor Black Bay One 79540 features a 22 mm lug width, a specific dimension reflecting the proportions of the 39.5 mm case. Width should be measured in the internal space between the lug pins using a digital calliper, ensuring precise tolerance for aftermarket strap purchases.

To maximise this unique timepiece, we recommend an alligator strap in deep blue or black that highlights the gradient dial, or vegetable-tanned calf leather that develops patina parallel to the bronze bezel's oxidation. For intensive water use, an FKM rubber solution with deployant clasp ensures complete 200-meter waterproofing.

Strap change is performed using a two-ended spring bar. Position the watch on a soft pad, insert the small tool into the spring bar hole to compress it, extract the pin, and slide out the previous strap. The new 22 mm strap is inserted by aligning the pin within the lugs and pressing until you hear a click.

Yes, any strap with the correct 22 mm lug width is compatible with the 79540. It is crucial to verify manufacturing tolerance: width must be 22 mm (±0.1 mm) in the section housing the spring bar, avoiding lateral play or friction against the lugs.

A quality leather strap on a Tudor of this significance has a lifespan of 3-5 years with ordinary use, varying according to humidity exposure, perspiration and UV rays. Vegetable-tanned leathers age with elegance and can be professionally restored. Calf and alligator maintain structural integrity longer if subjected to periodic maintenance (cleaning, conditioning).
