Frequently asked questions

What is the lug width of the Omega Constellation 123.25.24.60.55.001?

The lug width of the Omega Constellation 123.25.24.60.55.001 is 18 mm. This dimension is specific to this 24 mm bicolour model and it is essential to verify it precisely before ordering an aftermarket strap, as even minor discrepancies can cause misalignment.

Which type of strap best suits the bicolour red gold and steel Constellation 123.25.24.60.55.001?

Dark brown or black alligator remains the most conservative and elegant choice, emphasizing the sophistication of the mother-of-pearl dial. Vegetable-tanned calf offers a more casual and characterful alternative, while shell cordovan ensures durability and a noble patina that evolves over time.

How do you change the strap on the Omega Constellation 123.25.24.60.55.001?

Remove the watch from your wrist and use a spring bar tool to gently push the pins inward, thereby releasing the strap from the case lugs. Insert the new strap by aligning the holes with the pins, then snap the spring bar into position. Ensure the strap is securely attached before wearing the watch.

Are 18 mm aftermarket straps compatible with the 123.25.24.60.55.001?

Yes, any 18 mm strap of adequate construction quality is compatible with your Constellation. We recommend choosing specialized craftsmen who understand the proportion between the 24 mm case and the strap, ensuring a cohesive aesthetic result.

How long does a leather strap last on the Omega Constellation 123.25.24.60.55.001?

A quality leather strap (alligator, calf, cordovan) typically lasts between 3 and 7 years, depending on daily use, moisture exposure, and maintenance. Alligator and cordovan are more resistant than standard calf. The warranty offered by Casati Milano is 18 months, with the possibility of regeneration or replacement.
