Frequently asked questions

What is the exact lug width of the Omega Constellation 123.15.24.60.57.001?

The lug width of the 123.15.24.60.57.001 model is 18mm. This measurement is crucial for purchasing a compatible strap: a wider or narrower lug width will not fit correctly onto the case lugs and will result in mechanical instability. Always verify with a digital caliper the distance between the lugs before ordering a replacement strap.

What is the best strap for the Omega Constellation 123.15.24.60.57.001?

For this Constellation, we recommend vegetable-tanned alligator (brown, tobacco or grey) or burgundy shell cordovan. These materials respect the elegant proportions of the 24mm case and the aesthetic signature with steel griffes. Avoid rubber or NATO straps that are too thick, as they would visually weigh down the watch. The final choice depends on the context of use: alligator for formal occasions, calf for versatility, cordovan for dramatic effect.

How do you change the strap on an Omega Constellation?

To change the strap on your 123.15.24.60.57.001, use a spring bar tool (a specific tool with two pointed ends). Position the watch on a stable surface, insert the tip of the tool into the small slot of the lug from one side and press gently downward: the internal spring will retract and you will be able to extract the spring bar. Repeat from the other side. Clean the lugs of any old leather residue, then insert the new strap by sliding the lugs into the slots and pushing the spring bar into position until you hear the locking click. If you are unsure, consult a professional watchmaker to avoid damage.

Is an aftermarket strap compatible with the 123.15.24.60.57.001 model?

Yes, as long as the strap is specifically designed for an 18mm lug width. Many artisanal straps (such as those offered by Milano Straps) are fully compatible with the 123.15.24.60.57.001 and offer construction quality, choice of materials (alligator, calf, cordovan) and customizations impossible with original Omega straps. Always verify that the spring bar is of the correct length (standard 18mm) and that the strap is shaped for neck-to-case, not flat.

How long does a leather strap last on the Constellation 123.15.24.60.57.001?

Durability depends on the material and usage. An alligator or calf leather in vegetable tanning, with moderate daily use, lasts 18-30 months before requiring replacement due to wear concentrated in the wrist curve area. Shell cordovan is more durable (24-36 months). Frequent exposure to direct water, extreme heat and friction accelerates wear. An artisanal Milano Straps strap benefits from an 18-month warranty and can be restored (refurbished) after a few years at a cost lower than complete replacement, especially in vegetable tanning where the acquired patina has aesthetic value.
