Frequently asked questions

What is the exact lug width of the Tudor Black Bay One 79683-0007?

The Tudor Black Bay One 79683-0007 has a lug width of 22mm, measured internally between the case shoulders. This specific width ensures optimal proportions with the 41mm case diameter. Always verify with a digital calliper before ordering a strap, measuring from inner edge to inner edge.

Which strap material best complements the bi-colour yellow gold and steel case?

We recommend high-grade alligator in dark cognac or shell cordovan: these materials do not visually compete with yellow gold and develop a patina that enhances the case's sophistication over time. Vegetable-tanned calf leather is a valid alternative for daily wear dynamics.

How do I change the strap on my Tudor Black Bay One 79683-0007?

The procedure is straightforward: remove the spring bars at the upper and lower lugs using a spring bar tool, extract the old strap, align the new strap's holes with the bars, and press until you hear the locking click. The process takes approximately 2-3 minutes for experienced users; consult a watchmaker if uncertain.

Can I use an aftermarket 22mm strap on this watch?

Yes, any strap with certified 22mm lug width is compatible, provided the width tolerance remains within 22.5mm. Milan Straps' artisanal straps are tested for this measurement and produced to luxury standards. Always verify that the strap was specifically manufactured for 22mm width, not approximate measurements.

How long does a leather strap last on a daily-wear watch?

A high-quality artisanal leather strap, made from noble materials such as alligator or shell cordovan, typically lasts 3-5 years of daily wear. Longevity depends on maintenance, frequency of wear, climate, and tanning method. Vegetable-tanned leather tends to age aesthetically better than industrial leather, developing characteristic patina.
