Frequently asked questions

What is the lug width of the Omega Aqua Terra 220.32.43.22.10.001?

The Omega Aqua Terra 220.32.43.22.10.001 has a lug width of 21mm, verifiable by measuring the internal distance between the two case attachment points with a digital caliper. This specification determines compatibility with dedicated artisanal straps.

Which strap is best for the Aqua Terra 220.32.43.22.10.001?

For this 43mm case in titanium and ceramic, a vegetable-tanned alligator offers aesthetic balance and longevity. Pearly grey calf amplifies the modernity of the hybrid construction. For sports use, a Cordura canvas NATO in blue or an FKM rubber strap with textured finish ensure practicality without visual compromise.

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

Remove the lug pins using a spring bar removal tool (fork-style extractor). Position the flat end of the extractor under the spring bar, gently press upward to compress the internal spring, and extract the pin. Repeat on the opposite lug. Install the new strap following the reverse procedure, verifying correct spring bar engagement on both lugs.

Can I use an aftermarket strap compatible with the Aqua Terra 220.32.43.22.10.001?

Yes, any strap with 21mm lug width is compatible with the Aqua Terra 220.32.43.22.10.001. Artisanal straps are crafted in vegetable-tanned leather, alligator, NATO, and rubber, with factory-fitted quality spring bars for precise fitment.

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

A quality vegetable-tanned leather strap, worn daily, lasts 3-5 years before replacement is needed. Longevity depends on environmental humidity, frequency of wear, and care (periodic drying and conditioning with specific products). Vegetable-tanned alligator ages more nobly than calf, developing patina and maintaining structure beyond 4 years.
