What I'm asked about the Tudor Black Bay Chrono 39 Bumblebee 79310N

What strap size does the Tudor Black Bay Chrono 39 Bumblebee 79310N take?

The Tudor Black Bay Chrono 39 Bumblebee 79310N needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Tudor Black Bay Chrono 39 Bumblebee 79310N 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 Chrono 39 Bumblebee 79310N?

Yes, in 20 mm leather. On a 39 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Tudor Black Bay Chrono 39 Bumblebee 79310N?

A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
