Frequently asked questions

What is the lug width of the Omega Constellation 123.20.24.60.55.006?

The lug width is 18 mm. This dimension is specific to this ladies' model: make sure to order straps that are 18mm compatible with this exact measurement.

Which strap is recommended for the Omega Constellation 123.20.24.60.55.006?

For this timepiece we recommend cognac or tobacco alligator, or vegetable-tanned calf. Alligator enhances the warmth of yellow gold; calf offers natural aging over time. Both materials pair elegantly with the mother-of-pearl dial.

How do you change the strap on the Omega Constellation 123.20.24.60.55.006?

Use a dedicated tool (spring bar tool) to remove the spring bars at the lugs. Position the tool on the spring, gently push inward to release the tension, then extract the bar. Repeat for both attachments. Install the new strap by reversing the procedure.

Is it possible to fit a quality aftermarket strap on the Constellation 123.20.24.60.55.006?

Yes, absolutely. Milano Straps artisanal straps, crafted in alligator, calf and vegetable tanning, are fully compatible with the 18 mm lug attachments on this model. Artisanal construction quality guarantees superior fit compared to original straps.

How long does a leather strap last on this watch?

A quality alligator or calf strap lasts 3-5 years with daily wear. Longevity depends on sun exposure, humidity and frequency of use. Milano Straps include an 18-month warranty and are crafted using artisanal methodologies that extend durability over time.
