Frequently asked questions

What is the exact lug width of the Omega Aqua Terra 2565.78.00?

The Omega Aqua Terra 2565.78.00 features standardized lugs with a 20mm width. To verify this measurement, you can insert a tape measure between the two spring bars positioned at the case ends. A 20mm strap ensures perfect compatibility with this model without requiring any modifications.

Which strap is best suited for the Aqua Terra 2565.78.00?

For your Aqua Terra 2565.78.00, we recommend a dark brown alligator strap or vegetable-tanned calf leather. Alligator preserves the nautical elegance of the teak dial, while calf develops a natural patina over time, perfect for those seeking a timepiece with character and evolution. A second valid option is black calf leather for maximum versatility.

How do you change the strap on an Omega Aqua Terra 2565.78.00?

Changing the strap on the Aqua Terra 2565.78.00 can be done manually: use a spring bar tool to compress the spring at the case ends and remove the lugs, then repeat the operation in reverse with the new strap. If you are not experienced, the Casati Milano atelier offers a professional strap change service, ensuring correct installation and case protection.

Can I use an aftermarket strap on an Omega Aqua Terra 2565.78.00?

Yes, any superior quality 20mm strap is compatible with the Aqua Terra 2565.78.00. Verify that the spring bar hole has an internal diameter of at least 1.5mm and that the strap is made from premium materials such as alligator, calf leather, or technical rubber. On milanostraps.it you will find a selection of 20mm straps specifically compatible with this model.

How long does a leather strap last on an Omega Aqua Terra 2565.78.00?

A premium leather strap, made from alligator or calf, maintains functional integrity for 4-6 years with careful daily use. Durability depends on exposure to moisture, frequency of use, and maintenance: occasional protection with specific balm significantly extends the strap's life. Casati Milano straps include an 18-month warranty and can be subject to structural servicing after the first year.
