What I'm asked about the Oris TT3 01 774 7611 7784-Set

What strap size does the Oris TT3 01 774 7611 7784-Set take?

The Oris TT3 01 774 7611 7784-Set needs 28 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Oris TT3 01 774 7611 7784-Set 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 TT3 01 774 7611 7784-Set?

Yes, in 28 mm leather. On a 46 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Oris TT3 01 774 7611 7784-Set?

A 28 mm box calf. 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.
