What I'm asked about the Tudor Black Bay 79250BA

What strap size does the Tudor Black Bay 79250BA take?

The Tudor Black Bay 79250BA needs 23 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Tudor Black Bay 79250BA be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Tudor Black Bay 79250BA?

Yes, in 23 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 43 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 23 mm: write to me and I'll make it.

Which strap do you recommend for the Tudor Black Bay 79250BA?

Rubber if you wear it in the water; otherwise a 23 mm calf strap, full thickness. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
