Frequently asked questions

What is the exact lug width of the Omega Constellation 111.25.23.60.55.002?

The Omega Constellation 111.25.23.60.55.002 has a lug width of 18mm. This is the distance between the inner shoulders of the case where the strap is inserted. You can easily verify it by placing a ruler on the inner part between the two strap attachments.

What is the best strap for the Constellation two-tone with mother-of-pearl dial?

For the Constellation 111.25.23.60.55.002 we recommend a dark brown alligator strap or black calf leather. Alligator enhances the warmth of the rose gold case, while black calf creates a formal contrast with the two-tone. A dove grey calf is perfect for highlighting the mother-of-pearl dial.

How do you change the strap on an Omega Constellation 22.50mm?

To change the strap on your Constellation 111.25.23.60.55.002, use a spring bar tool to compress the internal springs of the lugs. Remove the old strap by pushing the spring bar downward from one end, then insert the new strap by aligning the lugs with the case attachments. Repeat the operation on the other side with gentle movements.

Can I use an 18mm aftermarket strap on my Constellation 111.25.23.60.55.002?

Yes, any strap with an 18mm lug width is compatible with your Constellation 111.25.23.60.55.002. Handcrafted straps available online are made specifically for this size and guarantee a perfect fit in the case attachments.

How long does a leather strap last on a women's watch like the Constellation?

The lifespan of a leather strap depends on usage and the quality of the tanning. A strap in alligator or artisanal calf leather can last 3-5 years with moderate daily use. Straps with vegetable tanning develop a natural patina and can last longer. To extend the life of your strap, avoid prolonged exposure to water and direct sunlight.
