What I'm asked about the Omega Aqua Terra 231.50.30.20.55.002

What strap size does the Omega Aqua Terra 231.50.30.20.55.002 take?

The Omega Aqua Terra 231.50.30.20.55.002 needs 14 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Omega Aqua Terra 231.50.30.20.55.002 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 231.50.30.20.55.002?

Yes, in 14 mm leather. On a 30 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Omega Aqua Terra 231.50.30.20.55.002?

A 14 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.
