Strap for Tudor Black Bay One 79663

The Tudor Black Bay One 79663 features a 20mm lug width, which is the standard space between the case lugs where the strap attaches. This width is proportionate to the 41mm case diameter and is essential for correct fit and balanced strap aesthetics.

For the 79663, we recommend fine-grained alligator for formal elegance, vegetable-tanned shell cordovan for evolving patina, or rubber/technical fabric to emphasise the tool watch DNA. Each material dialogues differently with the brushed bronze dial and yellow gold case.

Use a spring bar tool (small metal implement) to gently remove the elastic pins from the lugs. Insert the spring bar tool into the small slot beneath the lug, press to compress the pin, and simultaneously pull the strap out. Repeat on the other side, then install the new strap by reversing the process.

Yes, any strap with a 20mm lug width is compatible with the Tudor Black Bay One 79663. Aftermarket straps offer greater material choice and can be personalised in size, length, initials, and thread colour, allowing authentic aesthetic expression compared to factory straps.

A naturally-tanned leather strap typically lasts 3-5 years with daily wear, developing characteristic patina. Longevity depends on UV exposure, humidity, frequency of wear, and periodic conditioning. Robust leathers such as shell cordovan and alligator tend to last longer while maintaining structural integrity.
