What I'm asked about the Omega Aqua Terra 231.55.34.20.55.001

What strap size does the Omega Aqua Terra 231.55.34.20.55.001 take?

The Omega Aqua Terra 231.55.34.20.55.001 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 Omega Aqua Terra 231.55.34.20.55.001 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 Omega Aqua Terra 231.55.34.20.55.001?

Yes, in 20 mm leather. On a 34 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Omega Aqua Terra 231.55.34.20.55.001?

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

Frequently asked questions

How long does a leather strap typically last on the Omega Aqua Terra 231.55.34.20.55.001?
