Strap for Black Bay 39 S&G / Champagne / Bracelet

The lug width of the Tudor Black Bay One 79663-0005 is precisely 20mm. This measurement indicates the distance between the two metal lugs and determines compatibility with aftermarket straps. You can verify this by measuring the internal distance between the lugs with a digital calliper: all straps compatible with 20mm lug width will install without adapters.

For the 79663-0005, ideal options include: black satin alligator for formal wear, cognac vegetable-tanned calf for warm-season settings, burgundy shell cordovan for sophisticated elegance, and grey-charcoal FKM rubber for water sports. The choice depends on intended use and the chromatic harmony desired with the two-tone yellow gold and steel case.

The 79663-0005 strap is replaced by removing the metal lugs from the case lugs using a dedicated spring bar tool. Position the flat end of the tool under the lug, apply gentle pressure and pull sideways. Install the new strap by aligning the metal lugs through the lug holes and ensure the strap is secure before wearing the watch.

Yes, the 79663-0005 with 20mm lug width is fully compatible with all standard 20mm artisanal straps. You can choose from alligator, calf, shell cordovan, rubber, NATO fabric and even metal, as long as specifically sized for 20mm lugs. Avoid undersized (18-19mm) or oversized (21-22mm) straps.

A well-made leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3-5 years with moderate daily use. Longevity depends on leather type, intensity of use, moisture exposure and buckle/clasp wear. A vegetable-tanned leather strap ages nobly, developing characteristic patina without degrading rapidly like industrial tannages.
