Strap for Tudor Black Bay Chronograph 79363N

The lug width of the Tudor Black Bay Chronograph 79363N is 22mm. This dimension is determined by the geometry of the 41mm case and the yellow gold lugs. It is essential to verify this measurement before purchasing a strap to avoid incompatibility and damage to the case lugs.

The ideal strap depends on intended use. Glossy alligator offers maximum visual refinement, vegetable-tanned calf develops natural patina over time, NATO is practical for those requiring versatility. For the two-tone aesthetic of the case, we recommend medium brown or navy tones that dialogue with the black bezel and dial.

Strap replacement is accomplished via removable lugs (spring bars). Using the appropriate tool (spring bar remover), gently compress the spring bars and extract them from the case. Position the new strap by aligning the holes with the lugs and reinsert the spring bars until they click into place. This procedure requires precision to avoid damaging the case attachments.

Yes, provided the strap is manufactured with the correct lug width (22mm) and the spring bars are compatible with the case lugs. Artisanal aftermarket straps often offer superior materials compared to original accessories, such as genuine alligator, shell cordovan, and vegetable-tanned leather with customised finishing.

Longevity depends on material and usage. A well-maintained alligator or shell cordovan strap lasts from 3 to 7 years. Smooth calf has a lifespan of 2 to 4 years. Frequent exposure to salt water, sweat and direct sunlight significantly shortens useful life. Proper drying after moisture contact and periodic rest of the strap extend its longevity.
