Frequently asked questions
What is the exact lug width of the Omega Constellation 123.55.24.60.55.004?
The <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">lug width</a> of the Constellation 123.55.24.60.55.004 is 18 millimetres. This measurement represents the distance between the two lugs on the case and is essential for choosing a compatible strap. For verification, use a calliper measuring from the inside of one lug to the other on the case.
What strap material do you recommend for the Constellation 123.55.24.60.55.004?
Brown <a href="https://milanostraps.it/pages/termine-glossario/alligatore">alligator</a> is the classic choice for this model, thanks to its regular grain that dialogues elegantly with the mother-of-pearl dial. <a href="https://milanostraps.it/pages/termine-glossario/shell-cordovan">Shell cordovan</a> offers superior depth if you are seeking a patina that evolves over time. For a conscious choice, vegetable-tanned <a href="https://milanostraps.it/pages/termine-glossario/concia-vegetale">calf leather</a> maintains excellent tactile qualities without environmental compromise.
How do you change the strap on an Omega Constellation 24mm?
Remove the watch from your wrist and place it on a stable surface. Use a small lever (spring bar tool) to gently push inward the small metal pin located under the strap in the lug seat. Once released, the strap slides out from the lugs. To fit the new strap, align the holes and insert the metal pin into the lugs by pushing until it locks into place.
Does the Constellation 123.55.24.60.55.004 accept aftermarket 18mm straps?
Yes, any quality 18mm strap is compatible with the Constellation 123.55.24.60.55.004.

How long does a leather strap last on a watch worn daily?
Durability depends on the quality of the leather and the intensity of use. An <a href="https://milanostraps.it/pages/termine-glossario/alligatore">alligator</a> or well-maintained <a href="https://milanostraps.it/pages/termine-glossario/shell-cordovan">shell cordovan</a> strap lasts on average 4-6 years with daily wear. A quality <a href="https://milanostraps.it/pages/termine-glossario/concia-vegetale">vegetable-tanned</a> strap, exposed to constant humidity, sun and heat, develops a fascinating patina but should be regenerated every 2-3 years. The key to longevity is rotation: alternating multiple straps significantly extends the life of each one.
