Frequently asked questions

What is the lug width of the Omega Constellation 123.13.35.60.52.001?

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of this Constellation is 20mm. This measurement is fundamental for selecting the correct strap: the case lugs are spaced exactly 20mm apart, a classic size for medium-sized wristwatches. Always verify the width by measuring millimeters between the inner pins before ordering.

What is the best strap material for the Omega Constellation 123.13.35.60.52.001?

For this model we recommend <a href="/pages/termine-glossario/alligatore">alligator</a> in <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> or English bull leather. Alligator reflects the understated elegance of the Constellation, with a regular texture that contrasts beautifully with the brushed steel case. Leather, simpler in nature, develops a natural patina over time. Both materials enhance the classic character of this reference without adding visual noise.

How do I change the strap on my Omega Constellation 123.13.35.60.52.001?

The strap is removed by extracting the spring bars that connect the lugs to the case. Position the watch on a stable surface, use a spring bar tool to release the pins from the lug holes, remove the old strap and insert the new one. Ensure the pins are fully seated within the new passants. If your Constellation is equipped with an integrated <a href="/pages/termine-glossario/deployante">deployante</a> (on some references in the line), the procedure is identical but simpler since the buckle remains fixed.

Are Milano Straps aftermarket straps compatible with the Constellation 123.13.35.60.52.001?

Yes, completely. All <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm straps</a> from Milano Straps are designed to fit perfectly on the lugs of your Constellation. Our craftsmen guarantee precise tolerances on the passants for a fit without play. You can customize by size, color, initials and stitch type: every strap is tested before shipping.

How long does a leather strap last on an Omega Constellation?

A quality leather strap, such as those by Milano Straps crafted in <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> or vegetable-tanned alligator, lasts 3 to 5 years with daily use, depending on sun exposure, humidity and maintenance. <a href="/pages/termine-glossario/concia-vegetale">Vegetable tanning</a> develops patina over time, enriching it visually. We recommend not immersing the Constellation with a leather strap and letting it air dry after rain exposure. With care, every artisanal strap improves in appearance over the years.
