What I'm asked about the Oris TT1 01 674 7659 4764

What strap size does the Oris TT1 01 674 7659 4764 take?

The Oris TT1 01 674 7659 4764 needs 25 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Oris TT1 01 674 7659 4764 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 TT1 01 674 7659 4764?

Yes, in 25 mm leather. On a 45 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Oris TT1 01 674 7659 4764?

A 25 mm calf strap, for every day. 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.
