Frequently asked questions

What lug width does the Omega Aqua Terra 231.53.43.22.02.001 have?

The Omega Aqua Terra 231.53.43.22.02.001 has a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 20mm, an established standard for medium-to-large models in the collection. This width allows compatibility with a broad range of artisanal straps.

What is the most recommended strap for the Aqua Terra in rose gold?

To enhance the rose gold case of the 231.53.43.22.02.001, we recommend <a href="/pages/termine-glossario/alligatore">alligator</a> in cognac or dark brown tones with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>, which creates warm contrast while maintaining formal elegance. Alternatively, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> in burgundy for natural patina development over time.

How do you correctly measure the lug width of a watch?

Measure between the internal lugs of the case (where the strap connects). For the 231.53.43.22.02.001, position a digital caliper perpendicular to the lugs: the result should be 20mm. Also verify the desired total length (wrist circumference + 1–1.5cm for comfort).

Is the strap of the 231.53.43.22.02.001 compatible with other watches?

Yes, any 20mm strap is compatible, but consider aesthetics: the Aqua Terra in rose gold pairs better with warm leather tones (cognac, bordeaux, tobacco). Avoid cool contrasts that diminish the legibility of the style.
