Frequently asked questions
What is the lug width of the Omega Constellation 123.25.24.60.55.009?
The lug width is 18mm. This means the space between the lugs (the attachment points of the bracelet to the case) is exactly 18 millimetres. It is essential to verify this measurement before choosing an aftermarket strap to ensure perfect compatibility and maintain the aesthetic balance of the case.
Which strap material is best suited to the Constellation 123.25.24.60.55.009?
Alligator in cognac or light brown shades is the ideal choice: it amplifies the sophistication of rose gold and dialogues perfectly with the compact dimensions of the case. Shell cordovan or vegetable-tanned calf leather are also excellent, especially if you prefer a strap that ages gracefully over time.
How do you change the strap on a 24mm Constellation?
To change the strap you need to remove the side lugs that secure the bracelet to the case lugs. Usually a dedicated tool (spring bar tool) is required to compress the internal spring of the lug. We recommend having the operation performed at a specialized atelier to avoid damage to the case, especially if it is in rose gold.
Is an 18mm strap compatible with other Omega models?
Yes, any Omega watch with an 18mm lug width is compatible. However, the final aesthetic depends on the case diameter: the 123.25.24.60.55.009 has a 24mm case, so straps designed for this proportion will maintain overall visual harmony.
How long does a leather strap last on a Constellation?
A high-quality alligator or shell cordovan strap lasts between 3 and 5 years with moderate daily wear. Longevity depends on the wear of the outer edge, humidity and maintenance. Artisanal Casati Milano straps include an 18-month warranty and can be restored with specialized renovation services after a few years of use.
