Frequently asked questions

What is the lug width of the Omega Constellation 123.20.24.60.55.007?

The lug width of this model is exactly 20 mm. It is measured center-to-center of the attachment holes on the case. This dimension is specific to the 24 mm Constellation and is critical to ensure that aftermarket straps fit correctly without gaps or binding.

Which strap is most suitable for the Omega Constellation 123.20.24.60.55.007?

Alligator with vegetable tanning is the most visually coherent choice: the regular texture mirrors the sophistication of the mother-of-pearl dial, creating aesthetic continuity. Smooth calf leather in cognac or beige tones also pairs perfectly with the refinement of the rose gold and steel case.

How do I change the strap on my Constellation 123.20.24.60.55.007?

Use a spring bar tool or watch-specific tool to push inward the metal pin (spring bar) that secures the strap to the case. Push from one side, remove the old strap, and insert the new one by aligning the strap holes with the lugs on the case. The procedure requires care to avoid scratching the lugs.

Can I use an aftermarket strap on an Omega Constellation 24mm reference 123.20.24.60.55.007?

Yes, provided the strap has a lug width of 20 mm. Handcrafted aftermarket straps are fully compatible and offer greater styling freedom than the integrated original bracelet, while maintaining the same construction quality with personalized material selection.

How long does a leather strap last on this Omega watch?

A quality leather strap, with vegetable tanning or alligator, typically lasts 3–5 years with ordinary maintenance (avoid prolonged moisture, dry after swimming). Longevity depends on use: formal contexts (few days per week) extend the lifespan to 7 years, while intense daily use reduces the cycle to 2–3 years.
