The Heritage

The Constellation represents one of Omega's iconic collections, characterized by the distinctive design with integrated claws on the case. This reference 1392.30.00 model is powered by the Omega 2520 caliber with hour, minute, second and date functions. The construction features a case with a claw-based glass fixation system, a hallmark of the Constellation line.
Made to Measure

The strap for this watch is made to measure

On the Omega Constellation the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

What is the best strap for the Omega Constellation 1392.30.00?

For the Constellation 1392.30.00 we recommend polished alligator for gold/steel examples: the fine grain enhances the reflections of the precious case, creating a natural aesthetic harmony. Alternatively, shell cordovan represents a distinctive and sophisticated option, ideal for a patina that evolves over time. For the more sporty versions, satin FKM rubber ensures practicality without compromising elegance.

How do I change the strap on my Constellation 1392.30.00?

The change is made by acting on the spring bars that connect the strap to the case. Use a dedicated tool – a lug width tool or a small flat screwdriver – to compress the small internal hook of the spring bar, releasing the old strap. Then insert the new strap by aligning the lug holes with the spring bars, pushing until you feel the closure click. Proceed with caution to avoid scratches on the case.

How long does a leather strap last on an Omega Constellation 1392.30.00?

The durability depends on the quality of the leather, daily use and maintenance. A well-crafted alligator or calf leather strap typically lasts 3-5 years of regular use before showing obvious signs of wear. Vegetable tanning evolves gracefully, developing a beautiful patina. To extend longevity, avoid prolonged exposure to direct sunlight and excessive humidity, and apply leather conditioner every 12-18 months.

The right strap isn’t chosen. It is built, together.
