Frequently asked questions

What is the lug width of the Tudor Black Bay One 79583-0002?

The Tudor Black Bay One 79583-0002 features a 20mm lug width. This dimension is specific to the compact 32mm case format and ensures optimal proportions between the case and strap. It is not advisable to mount straps with 18mm or 22mm lugs, as this would compromise the aesthetic integrity of the timepiece.

Which type of strap pairs best with the Black Bay One 79583-0002?

Alligator with vegetable tanning in havana or cognac tones is the most natural choice to enhance the yellow gold mixed case. Alternatively, black calf leather with vegetable tanning creates an elegant contrast. For a sporty approach, a navy NATO or black rubber strap maintains the original character of the Black Bay One whilst offering daily practicality.

How do I change the strap on the Tudor Black Bay One 79583-0002?

Strap replacement requires removal of the two spring bars that secure the lugs to the case. Use a dedicated spring bar tool to gently compress the internal spring and extract the bar from one side. Once both bars are free, the strap detaches. For fitting a new strap, insert the bar from the same direction, ensuring the spring mechanism is correctly positioned within the lug holes.

Are aftermarket straps compatible with the Tudor Black Bay One 79583-0002?

Yes, any artisan strap with a 20mm lug width is compatible with the Black Bay One 79583-0002. The standard spring bars used by Tudor are compatible with quality aftermarket straps. We recommend alligator, shell cordovan, or vegetable-tanned calf straps to maximise the aesthetic potential of the timepiece.

How long does a leather strap last on the Tudor Black Bay One 79583-0002?

The lifespan of a leather strap depends on material quality and usage intensity. Premium alligator or shell cordovan with vegetable tanning typically lasts 3–5 years of daily wear before replacement becomes necessary. The patina that develops naturally is desirable, but once the strap shows significant wear or tearing, replacement is recommended. Casati Milano artisan straps include an 18-month warranty.
