What I'm asked about the Oris Divers 65 01 733 7720 4388-Set LS

What strap size does the Oris Divers 65 01 733 7720 4388-Set LS take?

The Oris Divers 65 01 733 7720 4388-Set LS needs 21 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Oris Divers 65 01 733 7720 4388-Set LS 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 Oris Divers 65 01 733 7720 4388-Set LS?

Yes, in 21 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 42 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 21 mm: write to me and I'll make it.

Which strap do you recommend for the Oris Divers 65 01 733 7720 4388-Set LS?

Rubber if you wear it in the water; otherwise a 21 mm calf strap, full thickness. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
