Strap for Black Bay 39 S&G - Diamond / Black / Bracelet

The lug width of the Tudor Black Bay One 79673-0001 is 20mm. This is the standard width between the spring bar pins that attach the strap to the watch lugs. It is measured perpendicular to the case, from the inside of one pin hole to the inside of the other.

For the Black Bay One 79673-0001, we recommend alligator leather in black or deep tones to enhance the two-tone aesthetic, or cognac calf to create chromatic dialogue with the yellow gold component. Shell cordovan represents the premium option for those seeking natural patina development. All straps must respect the 20mm lug width specification.

Strap replacement requires a specific tool (spring bar remover or thin screwdriver). Place the watch on a soft surface. From the inner side of the lug, gently push the spring bar pin outward until it is completely extracted. Repeat for the second pin. Insert the new pins into the compatible 20mm strap and reinsert into the watch, ensuring both pins are fully locked.

Yes, any strap with a 20mm lug width is compatible with the Black Bay One 79673-0001. Artisanal leather straps (alligator, calf, shell cordovan) or premium fabric offer longevity and aesthetic consistency with the watch's character. Always verify that the spring bars are adapted to the case width.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 8-12 years with ordinary maintenance. Durability depends on frequency of use, sun exposure, humidity, and leather care. Vegetable-tanned leathers develop natural patina and strengthen over time. It is advisable to maintain a reserve strap to alternate use and extend longevity.
