Frequently asked questions

What is the lug width of the Tudor Black Bay 7923?

The lug width of the Tudor Black Bay 7923 is 22 mm. This measurement is standardised for the model and corresponds to the internal distance between the lugs of the case. Always measure with a calliper to verify compatibility before purchasing a strap.

What is the best strap for the Tudor Black Bay 7923?

The choice depends on usage and aesthetic preference. For classic elegance: black alligator. For daily versatility: vitello in natural tones. For military authenticity: woven NATO. For genuine diving use: grey FKM rubber. All these materials are available in the 22 mm lug width.

How do I change the strap on the Tudor Black Bay 7923?

Insert a spring bar tool into the small opening between the lug and the strap, at the internal spring. Apply gentle downward pressure to release the spring and extract the previous strap completely. Align the new strap hole with the spring and press until you hear a click. Verify that the strap is fully locked before wearing the watch.

Is there an aftermarket strap compatible with the Tudor Black Bay 7923?

On milanostraps.it you will find a dedicated selection of handcrafted leather, NATO and rubber straps, customisable in sizes, initials and stitching thread. All straps are tested for mechanical compatibility with the 7923 model.

How long does a leather strap last on the Tudor Black Bay 7923?

The lifespan of a leather strap depends on material quality, tanning and usage. A high-quality leather strap (alligator, shell cordovan, full-grain vitello) typically lasts 3-5 years with moderate daily use. The natural patina that develops over time is part of the recommended aging process. At Casati Milano, every custom-made strap is covered by an 18-month warranty.
