FAQ

What is the lug width of the Omega Aqua Terra 220.12.41.21.01.002?

The lug width is exactly 20mm. This measurement is taken from the inner edge of one lug to the inner edge of the other lug. Always verify with a digital caliper before purchasing an aftermarket strap.

Which strap is best suited for the Omega Aqua Terra 220.12.41.21.01.002?

For maximum elegance we recommend alligator or shell cordovan, which complements the Teak dial. For versatile daily wear, vegetable-tanned calf or FKM rubber. For frequent water exposure, NATO fabric or textured grain rubber.

How do you change the strap on the Omega Aqua Terra 220.12.41.21.01.002?

Use a spring bar tool to push the metal lug pin and release the bayonet ring from the case. Insert the new strap until it clicks into place. Ensure the lug width is exactly 20mm for security.

Can I use aftermarket straps on this Omega?

Yes, provided the lug width is 20mm. Quality-certified straps constructed to sartorial standards ensure perfect compatibility with the bayonet rings of the Aqua Terra case.

How long does a leather strap last on the Omega Aqua Terra 220.12?

With monthly rotation and ordinary care, a quality leather strap (alligator, cordovan, calf) lasts 3–5 years before replacement is needed. Aging creates patina, not deterioration. FKM rubber lasts 5–8 years with minimal maintenance.
