What I'm asked about the Omega Aqua Terra 220.58.38.20.99.004
What strap size does the Omega Aqua Terra 220.58.38.20.99.004 take?
The Omega Aqua Terra 220.58.38.20.99.004 needs 19 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 220.58.38.20.99.004 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 220.58.38.20.99.004?
Yes, in 19 mm leather. On a 38 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Omega Aqua Terra 220.58.38.20.99.004?
A 19 mm calf strap, for every day. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
What strap material is most suitable for the Omega Aqua Terra Sedna Gold 38mm?
For this rose gold version we recommend alligator in neutral tones (brown, hazelnut) for classic elegance, or vegetable-tanned calf leather for those who appreciate natural patina. For sports use, a black NATO fabric or rubber strap with contrasting stitching maintains the Aqua Terra's nautical vocation.
Are 19mm aftermarket straps truly compatible with this Omega or must I purchase an official strap?
19mm aftermarket straps are completely compatible from a mechanical standpoint. Milano Straps offers a collection of artisanal alternatives in alligator, calf leather and rubber that combine superior construction quality to standard Omega pricing, with customization (initials, sizing, thread color) impossible through official channels.
What is the average lifespan of a leather strap for the Omega Aqua Terra?
A high-quality alligator or vegetable-tanned calf leather strap lasts 3-5 years with moderate daily use. Durability depends on the frequency of contact with water, sweat and movement. Milano Straps guarantees 18 months on bespoke Casati Milano straps, but real longevity is often superior thanks to leather selection and artisanal techniques.
