Frequently asked questions
What is the lug width of the Tudor Black Bay 79230B-0006?
The Tudor Black Bay 79230B-0006 features a 22mm lug width, measured as the internal distance between the two case lugs. This precise standard allows for the use of high-quality artisanal straps without compromises in fit and comfort.
What is the best strap for the Tudor Black Bay 79230B-0006?
The choice depends on intended use. For diving, an FKM rubber or technical NATO strap ensures functionality and durability. For civilian daily wear, vegetable-tanned calf leather offers discreet elegance and evolving patina. Alligator is inadvisable: a diving watch should not be burdened with excess aesthetic luxury.
How do I change the strap on the Tudor Black Bay 79230B-0006?
Place the watch on a soft surface. Using a spring bar removal tool (or carefully, a toothpick), gently push the spring bar upward from beneath on both sides. Once removed, the strap will come free. Reassembly follows the reverse process: align the lug apertures and reintroduce the spring bars.
Can I mount an aftermarket compatible strap on this model?
Yes, any strap with a 22mm lug width is compatible. Milano Straps offers artisanal <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-22mm">22mm lug width straps</a> ready from stock. Casati Milano atelier also creates bespoke straps with direct material selection and customisation (initials, thread colour).
How long does a leather strap last on an intensively used watch like the Black Bay?
A vegetable-tanned calf strap lasts approximately 18–24 months under intense daily use (manual work, humid environments). FKM rubber exceeds 3 years. Vegetable tanning develops controlled creasing that increases its appeal; the strap ages with dignity. Casati Milano guarantees 18 months on all bespoke straps.
