It features the Omega caliber 1376, a quartz movement certified chronometer by COSC, with a sapphire crystal and water resistance to 100 meters. The distinctive Constellation griffes protect the crystal while providing structural rigidity. The 18mm lug width accommodates various strap options without compromising construction.

Frequently asked questions

What is the lug width of the Omega Constellation 123.20.24.60.08.001?

The lug width of the Constellation 123.20.24.60.08.001 is 18mm. This is the internal space between the case lugs where the strap is inserted. To verify the measurement, position a digital caliper from inside to inside of the protruding case pins: the result must be exactly 18mm. This proportion is specific to the 24mm case and is optimal for women's wrists.

Which strap material is best suited for the Constellation 123.20.24.60.08.001?

Alligator remains the most elegant choice for the Constellation, as the scale texture perfectly complements the rose gold and steel mix. Alternatively, Riviera calf offers greater versatility and simpler maintenance, suitable for both formal contexts and daily wear. For those seeking practicality without aesthetic compromise, a NATO strap in polyamide in neutral tones (grey, black) remains a modern and functional choice.

How to change the strap on the Constellation 123.20.24.60.08.001?

To change the strap, you will need a spring bar removal tool (a small watchmaker's lever). Position the watch with the case facing upward, locate the end of the lug, insert the lever into the dedicated slot on the spring bar and gently pull toward you. The spring bar will snap off. Repeat on the other side. Insert the pins of the new strap into the lugs and push the spring bars until you feel the locking 'click'. If you lack experience, consult a competent watchmaker to avoid damage to the case.

Is a strap purchased from Milano Straps compatible with the Constellation 123.20.24.60.08.001?

Yes, provided it has been chosen with 18mm lug width. All straps catalogued by Milano Straps in the 18mm collection are compatible with the Constellation 123.20.24.60.08.001. Always verify that the strap has spring bar attachment for correct installation. If you desire a perfect fit and personalized leather consultation, the Casati Milano atelier offers bespoke service by appointment.

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

Durability depends on the material and use. High-quality alligator, with proper maintenance, maintains functionality for 5-7 years, developing a patina that increases aesthetic value over time. Riviera calf, more resistant to atmospheric agents, can last 6-8 years in daily use. All Milano Straps artisanal straps come with an 18-month warranty. Factors such as humidity, direct sun exposure, and regular maintenance (brushing with a dry cloth) influence longevity. The Casati Milano atelier provides assistance for extending strap life through restoration interventions.
