Strap for Heritage Black Bay Chronograph S&G / Champagne / Bracelet

The lug width of the Tudor Black Bay Chronograph 79363N-0007 is 22 millimetres. This measurement represents the distance between the two lugs on the watch case and determines compatibility with all standard strap options. It is essential to verify this measurement before purchasing an aftermarket strap to ensure a proper fit without play or forcing.

For the steel and yellow gold version, alligator leather with vegetable tanning is the ideal choice. A cognac or Tuscan brown alligator strap enhances the bicolour case combination, offering that chromatic dignity and tactile softness that amplify the watch's construction prestige. Valid alternatives include shell cordovan and English calf leather in bourbon or dark brown tones.

Strap replacement on the Black Bay Chronograph is achieved by removing the lateral pins using a spring bar remover tool, which facilitates compression of the internal springs. Once the pin is released, the old strap is withdrawn and the new one inserted, aligning the holes with the pins. The procedure requires care to avoid scratching the case lugs. If inexperienced, it is advisable to consult a qualified watchmaker.

Yes, any strap with a 22-millimetre lug width is compatible with the Black Bay Chronograph 79363N-0007. Quality aftermarket straps, particularly those in premium leather with certified vegetable or animal tanning, offer the opportunity to personalise the watch while maintaining elevated construction standards. It is essential to verify that the selected strap has the correct dimensions and adequately supports the weight of the bicolour case.

The durability of a leather strap depends on the tanning type and frequency of use. An alligator strap with vegetable tanning, subject to ordinary maintenance (drying after accidental contact, annual conditioning with specific creams), maintains structural integrity for 3–5 years of daily use. Shell cordovan, owing to its superior density, can last 7–8 years. Natural calf leather requires greater care but remains elegant for 2–4 years. Rubber or NATO straps show aesthetic wear but retain functionality well beyond 5 years.
