Frequently asked questions
What is the lug width of the Omega Aqua Terra 220.10.41.21.01.001?
The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Omega Aqua Terra 220.10.41.21.01.001 is 20mm. This width is standard for all current-generation 41mm Aqua Terra models and ensures compatibility with the entire range of artisanal straps at this specific measurement.
Which strap is best suited to the Omega Aqua Terra 220.10.41.21.01.001?
The ideal strap depends on your use: for everyday elegance, brown or black <a href="/pages/termine-glossario/alligatore">alligator</a> with steel <a href="/pages/termine-glossario/deployante">deployante</a> is recommended; for sport-casual wear, vegetable-tanned <a href="/pages/termine-glossario/concia-vegetale">calf leather</a> aged naturally; for swimming, rubber or NATO. The Aqua Terra welcomes any choice because its aesthetic neutrality is its strength.
How do I change the strap on my Omega Aqua Terra 220.10.41.21.01.001?
The Omega Aqua Terra uses standard spring bar attachments. Obtain a spring bar removal tool (or consult a professional), place the watch on a clean surface, gently press inward on one terminal of the spring bar and extract it from the lugs. Insert the new strap by snapping the spring bars into their seats. This operation requires precision: the Casati Milano atelier offers this service in 48 hours by appointment.
What aftermarket strap can I use with this lug width?
The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 20mm is compatible with any artisanal strap manufactured at this specific width. On milanostraps.it you will find <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm straps</a> in leather, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a>, alligator, rubber and NATO fabric, customizable for length, initials and thread colour. Every strap is crafted to watchmaking tailoring standards.
How long does a leather strap last on an Omega like the 220.10.41.21.01.001?
Durability depends on frequency of use, tanning method and climatic conditions. A quality calf leather strap (vegetable-tanned) supports 2-3 years of moderate daily wear; <a href="/pages/termine-glossario/alligatore">alligator</a> and <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> reach 4-5 years. Exposure to salt water and perspiration shortens service life. Casati Milano guarantees 18 months on artisanal straps; subsequent wear depends on use and preventive maintenance.
