Frequently asked questions

What is the lug width of the Tudor Black Bay Chronograph M79360N-0019?

The lug width of the Tudor Black Bay Chronograph M79360N-0019 is 22mm. This specification is critical when purchasing compatible straps: measuring the lug width means verifying the internal distance between the pins that connect the strap to the case lugs. An incorrectly sized strap creates tension and premature wear on both the leather and the case's lug attachments.

Which strap do you recommend for the Tudor Black Bay Chronograph M79360N-0019?

The recommendation depends on wrist anatomy and intended usage. For slender wrists, a natural alligator strap in 22mm with cognac or black tones amplifies the racing character without visual excess. For robust wrists, vegetable-tanned calf in deep burgundy creates aesthetic continuity with the dial. Shell cordovan is the optimal choice for those demanding longevity and living in humid climates: the dense horsehorseflesh develops magnificent patina and resists moisture far better than bovine leather.

How do you change the strap on a Tudor Black Bay Chronograph?

The procedure requires minimal tools: a spring bar tool or equivalent implement to remove the pins anchoring the strap to the case. Position the watch on a soft cloth to prevent scratches. Apply pressure with the tool against the pin until it releases from the lug seat, remove the old strap, and insert the new one by aligning the pins with the same lug seat. The procedure is reversible and requires no watchmaking expertise.

Can I use an aftermarket strap on this Tudor Black Bay Chronograph?

Yes, provided it is specifically constructed for the 22mm lug width and the buckle is compatible with the leather thickness. An aftermarket strap allows aesthetic and functional customisation that Tudor originals often cannot provide. Bespoke artisan straps guarantee superior tannage quality and construction precision compared to industrial batches, with warranty coverage up to 18 months.

How long does a leather strap last on a chronograph like the Black Bay Chronograph M79360N-0019?

Longevity depends on tannage method, climate, and daily wear patterns. A vegetable-tanned calf strap lasts 3–5 years with regular use (five days weekly) before requiring resizing or replacement. Shell cordovan lasts 6–8 years due to superior fibre density. Natural alligator has intermediate longevity (4–6 years). Regular maintenance—gentle cleaning with a damp soft cloth and annual conditioning with specialist balm—extends strap lifespan by 20–30%.
