Frequently asked questions

What is the lug width of the Tudor Black Bay 79220N?

The lug width of the Tudor Black Bay 79220N is 22 millimetres. This measurement is essential for selecting compatible straps. The measurement should be taken from the outer edge of one lug to the other, at the point where the strap rests on the integrated stainless steel lugs.

What is the best strap for the Tudor Black Bay 79220N?

The choice depends on usage and context. For a balanced combination of aesthetics and functionality, a medium brown or deep black alligator strap offers elegance and durability over time. For sports applications, aged calf leather or rubber are excellent alternatives. NATO straps preserve the watch's technical identity with chromatic versatility.

How do I change the strap on my Tudor Black Bay 79220N?

Strap replacement is performed using a dedicated tool (strap removal tool) to compress the springs that lock the lugs to the case. Work on a soft surface to avoid scratching the case. The new strap must have a 22 millimetre lug width to ensure complete compatibility and structural integrity.

Can I use aftermarket straps on my Tudor Black Bay 79220N?

Yes, any strap with a 22 millimetre lug width is compatible with the 79220N. Quality aftermarket straps, made from alligator, calf, shell cordovan or rubber, allow you to personalise the watch while maintaining complete structural safety. We recommend verifying the quality of the tanning and buckle finishes to ensure longevity.

How long does a leather strap last on the Tudor Black Bay 79220N?

Durability depends on leather quality and frequency of use. A high-quality alligator strap, crafted with vegetable tanning, typically lasts 4-6 years with daily wear. Aged calf leather offers similar durability. Rubber straps last longer, whilst NATO canvas straps are virtually unlimited. Proper maintenance and protection from extreme humidity significantly extend leather lifespan.
