Frequently asked questions

What is the lug width of the Tudor Black Bay One 79680-0001?

The Tudor Black Bay One 79680-0001 features a 22-millimetre lug width. This dimension is specific to the 41-millimetre case and determines compatibility with any aftermarket strap. To verify it, measure the distance between the two attachment pins protruding from the caseback.

What strap suits the Tudor Black Bay One best?

It depends on intended use. For formal elegance, a cognac or black alligator in vegetable tanning develops natural patina and resists wear. For marine environments, NATO straps in technical polyamide ensure rapid drying and salt-water resistance. For versatility, grey tortoiseshell leather combines suppleness with understated sophistication.

How do I change the strap on this case?

The 79680-0001 case uses removable spring bars. Equip yourself with a dedicated spring bar tool to gently lift the lug and slide the pin out of its seat. Insert the new strap, aligning the pins with the designated holes, then ensure they are firmly secured on both sides. Avoid improvised tools to prevent scratching the case.

Can I fit an aftermarket strap to the Tudor Black Bay One?

Yes, provided you respect the 22-millimetre lug width. Quality artisanal straps often deliver superior finishing, premium materials, and personalisation options (initials, custom stitching) compared to OEM accessories. Ensure the strap is crafted from full-grain leather or certified polyamide for durability.

How long does a leather strap last on a regularly worn watch?

An alligator or calf leather strap of quality, worn daily, typically lasts 3-4 years before visible wear appears (creasing, elasticity loss). Longevity depends on sun exposure, humidity, and wearing frequency. Vegetable-tanned leather develops pleasant patina over time, making wear part of its character. With maintenance (annual cleaning and conditioning), lifespan can extend to 5-6 years.
