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

The lug width of the Tudor Black Bay One 79663-0006 is 20 mm. This dimension represents the space between the case lugs and is the standard that allows the strap to attach correctly via the spring bars. Always verify that the ordered strap is calibrated to this exact measurement to avoid misalignment or poor fit to the wrist.

Black alligator or high-quality dark leather represent the most coherent choices with the aesthetic identity of the Black Bay One 79663-0006. Alligator, with its ordered scales, enhances the solidity of the bicolour case whilst maintaining a sober visual patina. Leather subjected to vegetable tanning develops over time a natural chromatic richness that dialogues elegantly with the yellow gold tones. For aquatic contexts, the FKM or Tropic rubber strap remains functionally superior.

Strap replacement requires the use of a specific tool called a spring bar remover. Position the watch on a stable support, insert the remover into the lateral slot of the spring bar and apply gentle pressure until the bar extracts completely. Repeat the operation for the second bar. Insert the new bars into the fresh strap and reinsert them into the lugs, checking that they are firmly fixed. Avoid impacts and excessive pressure that could damage the case.

Yes, all 20mm straps of quality construction built according to international standards are compatible with the Black Bay One. It is essential, however, to verify that the strap presents a clean edge finishing and a chromatic coherence worthy of the satin dial and the bicolour case. Straps crafted by specialised laboratories guarantee precision levels superior to generic industrial products.

A quality leather strap (alligator or calf), properly maintained, can last between 3 and 5 years before requiring replacement. Durability depends on environmental humidity, frequency of use, solar exposure and the practice of periodic cleaning. A rubber or fabric NATO strap exhibits faster wear but proves more economical to replace. To extend the life of the leather strap, it is recommended to dry it after water exposure and store it in environments with controlled humidity.
