Frequently asked questions

What is the exact lug width of the Omega Constellation 1392.10.00?

The lug width of the Constellation 1392.10.00 is 20mm. This measurement refers to the distance between the lugs (the rotation axes) that connect the case to the strap lugs. To verify it, use a digital caliper positioned perpendicularly to the lugs themselves.

Which strap material is most suitable for the Constellation 1392.10.00?

Alligator represents the most elegant choice for this two-tone model, as its regular texture perfectly complements the yellow gold of the case. Alternatively, vegetable-tanned calfskin develops a natural patina over time that visually enriches the watch while maintaining everyday versatility.

How do you change the strap of the Omega Constellation 1392.10.00?

To change the strap, use a spring bar tool (specific spring-loaded tool) to gently compress the lug pins. Insert the tip into the designated seat and press downward, creating the necessary space to remove the old strap. Repeat the operation from the opposite side, then insert the new strap by aligning the pins to the lug holes.

Are Milano Straps aftermarket straps compatible with the 1392.10.00?

Yes, all straps from the Milano Straps 20mm collection are compatible with the Constellation 1392.10.00. Each strap is made with appropriately sized pins and verified to fit precisely to the watch's lugs, guaranteeing safety and optimal aesthetics.

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

An artisanal strap in alligator or vegetable-tanned calfskin, properly maintained, lasts an average of 3-5 years with daily use. Longevity depends on the tanning method, frequency of water contact, and your cleaning routine. Milano Straps offers an 18-month warranty on all straps crafted by the Casati Milano atelier.
