Frequently asked questions

What is the lug width of the Tudor Black Bay Chronograph M79360N-0011?

The Tudor Black Bay Chronograph M79360N-0011 features a lug width of 22mm. This measurement refers to the internal distance between the two lugs (strap bars) of the case and is the exact specification required when selecting a compatible strap. All straps in our 22mm category are fully compatible with this model.

Which strap is most suitable for the Tudor Black Bay Chronograph M79360N-0011?

Given the sports-oriented character and racing aesthetic of the Black Bay Chronograph, we recommend vegetable-tanned leather straps with natural aging finish, or alligator leather for superior chromatic refinement. During summer months, a cotton bio-based NATO strap or a technical rubber model perfectly complements both the diving heritage of the movement and the robustness of the case.

How do I change the strap on the Tudor Black Bay Chronograph M79360N-0011?

Strap replacement involves removing the two lug pins (also called strap bars) using a dedicated tool or small screwdriver. Once the pins are extracted, the existing strap separates from the case lugs. The new strap, respecting the 22mm lug width, is reinstalled by threading the pins through the strap's eyelet holes. We recommend performing this operation on a soft surface, such as a microfibre cloth, to prevent case scratching.

Can I fit an aftermarket strap on this watch?

Absolutely. The Tudor Black Bay Chronograph M79360N-0011 is completely compatible with quality aftermarket straps, provided they respect the 22mm lug width specification. Artisanal straps in vegetable-tanned leather, alligator, or technical rubber install easily and allow you to personalise your watch's appearance without compromising its warranty, provided the case remains undamaged.

How long does a leather strap last on a sports watch like the Black Bay Chronograph?

A quality vegetable-tanned leather strap, with regular use, typically lasts 4-6 years before replacement becomes necessary. Wear is natural and imparts character through the strap's patina development. Factors such as sunlight exposure, moisture and frequency of use influence longevity. Alligator straps, being denser, tend to last longer. Periodic maintenance with dedicated products significantly extends strap life.
