Strap for Black Bay 31 S&G / Black - Diamond / Bracelet

The Tudor Black Bay One 79603-0006 features a lug width of 16 millimetres. This dimension is the fundamental specification to verify when purchasing a compatible strap, as it represents the physical space between the two lugs of the case. An incorrect lug width would result in lateral movement and instability of the strap during daily wear.

For the two-tone steel and yellow gold case of the 79603-0006, we recommend straps in cognac alligator or chocolate brown calf, which create visual harmonies with the original colour composition. Alternatively, a black rubber strap offers complete versatility for daily use, whilst deep blue alligator delivers sophistication for more formal occasions.

Strap replacement requires a quick reference guide specific to your model. The 16mm straps are mounted on the lugs via locking pins (spring bars): you need a small lever or precision tool to release the internal spring tension and slide out the old strap. To avoid damage to the case, we recommend entrusting this operation to a professional if you lack experience.
