Strap for Tudor Black Bay Chronograph M79360N

The Tudor Black Bay Chronograph M79360N features a lug width of 22mm, a standard dimension requiring specifically constructed straps for this measurement. The measurement must be taken between the inner lugs of the case, not on the outer tube.

The choice depends on usage and aesthetic preferences. Alligator offers formal elegance with ageing patina; vegetable-tanned calf guarantees durability and character over time; a ballistic NATO strap maintains the chronograph's sport-military DNA. On brushed steel, natural leather alligator or chocolate brown calf remain coherent choices.

Use a spring bar tool to gently remove the two spring bars from the case sides—this requires precision to avoid scratching the case. Once the old strap is removed, align the new strap holes with the lugs and reinsert the spring bars, pushing until they click. The procedure takes 2-3 minutes and requires no specialised tools.

Yes, provided the strap is constructed for a 22mm lug width. Quality artisanal straps made from vegan leather, alligator, or calf are entirely compatible. We recommend straps with adjustable keepers for personal fit and brushed steel buckles that harmonise with the case.

A quality vegetable-tanned calf strap, worn daily with moderation, lasts 3-5 years before replacement is needed. Alligator, thanks to finer and more resistant fibres, can exceed 5-7 years. Prolonged exposure to humidity, salty sweat, and intense heat reduces lifespan. Regular maintenance with specialist conditioner significantly extends strap life.
