Frequently asked questions

What is the lug width of the Omega Aqua Terra 220.10.41.21.02.002?

The Omega Aqua Terra 220.10.41.21.02.002 has a lug width of 20 mm. This width is standard for the 41 mm model and is essential to ensure proper compatibility with any aftermarket strap. Always verify this measurement before purchasing a replacement strap.

What is the best strap for the Omega Aqua Terra 220.10.41.21.02.002?

The ideal strap depends on your intended use. For elegance, we recommend vegetable-tanned alligator with caramelized patina, or burgundy shell cordovan for lasting durability. For practicality and water use, a vulcanized FKM rubber strap or synthetic NATO offers functionality without aesthetic compromise. Casati Milano personalizes every choice based on your wrist and individual preferences.

How do I change the strap on the Omega Aqua Terra 220.10.41.21.02.002?

Removing the original strap is straightforward: use a standard spring bar tool to remove the pins connecting the strap to the watch lugs. Insert the new strap by aligning one lug first, then the other, and verify that the pins click into place correctly. If you are not experienced, rely on a professional replacement service.

Are there aftermarket straps compatible with the 220.10.41.21.02.002?

Yes, numerous 20 mm aftermarket straps are compatible. Milanostraps offers a complete collection of 20 mm straps ready to ship, with options in alligator, calf, shell cordovan, and rubber. All Casati Milano products include an 18-month warranty and can be customized in sizes, initials, and thread color.

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

The lifespan depends on the tanning method and usage. Vegetable-tanned alligator lasts 3-5 years with moderate daily use; shell cordovan can exceed 7-8 years. FKM rubber lasts 5-6 years. A strap that gets wet regularly ages more quickly. Casati Milano guarantees all straps for 18 months and provides recommended maintenance to extend their lifespan.
