Frequently asked questions

What is the lug width of the Omega Aqua Terra 231.53.34.20.01.001?

The lug width is 20mm. It is measured by calculating the distance between the lug seats on the case. All compatible straps must respect this exact width to fit correctly without any overhang.

Which strap do you recommend for the 231.53.34.20.01.001 in yellow gold?

An alligator with vegetable tanning in cognac or natural brown tones pairs perfectly with yellow gold. Alternative: pearl grey calf for a cooling effect, or deep burgundy for evening occasions. Avoid straps that replicate yellow gold.

How do I change the strap on my Omega Aqua Terra?

Use a specific tool (Swiss Army knife or spring bar tool) to gently lift the elastic pin that supports the strap in the case lugs. Remove the old strap and insert the new one by snapping the spring bar into place. If you are uncertain, contact a trusted watchmaker.

Is the aftermarket strap from Milano Straps compatible with my Aqua Terra?

Yes, provided it is made in 20mm lug width. Online straps are immediately available; for a personalized experience with direct leather selection and custom sizes, contact us at the Casati Milano atelier by appointment.

How long does a leather strap last on a watch like this?

With regular use, a quality leather strap (alligator or calf with vegetable tanning) lasts 2-4 years. The duration depends on exposure to moisture, sweat and frequency of use. Milano Straps guarantees 18 months on all custom straps made by Casati Milano.
