Strap for Black Bay 31 Stainless Steel / Champagne - Diamond / Bracelet

The lug width of the Tudor Black Bay One 79600-0006 is 17 millimetres. This measurement is determined by the geometry of the 31-millimetre case and must be measured with precision, from inner edge to inner edge, to ensure that the strap fits perfectly into the lug slots without excessive play or obstruction during assembly.

The best strap depends on intended use and aesthetic preferences. Natural alligator emphasises the case's satin finish without competing visually. Vegetable-tanned calf develops an elegant patina with age. Shell cordovan offers superior tactile density. NATO or rubber straps are ideal for active contexts. Your choice should consider the environment and daily destination of the watch.

Position the watch on a flat surface with the lugs horizontal. Use a spring bar tool, inserting the flat blade into the narrow gap between the lug and the passant. Gently push outward to compress the internal spring, then withdraw the lug. Repeat on the opposite end. Reverse the process with the new strap, ensuring the springs lock securely into the slots.

Yes, any 17mm strap with correctly formed passants is compatible with the 79600-0006. However, the strap's build quality must be proportionate to the watch. Artisanal straps manufactured to precision tolerances (below 0.3mm) guarantee secure attachment and aesthetic coherence. Avoid generic straps that may present play in the passants or stress the lugs.

The lifespan of a leather strap depends on material quality, tanning method and usage. A quality artisan strap in vegetable-tanned calf, worn in normal daily conditions, typically lasts 3-5 years before replacement is warranted. Vegetable-tanned leather develops a patina that ages elegantly. Shell cordovan and high-quality alligator may last 5-7 years or longer. Wear accelerates in high-humidity environments or with prolonged exposure to perspiration or water.
