The Omega Constellation Manhattan 28 Quartz model 131.25.28.60.52.001 combines Sedna Gold and stainless steel in a 28mm case. Powered by the Omega 4061 quartz movement, it features the iconic griffes protecting the bezel, a domed sapphire crystal, and fixed rotating bezel. The 20mm lug width is specific to this model, requiring dedicated straps for customization beyond the integrated bracelet.

Frequently asked questions

What is the lug width of the Omega Constellation 131.25.28.60.52.001?

The Omega Constellation 131.25.28.60.52.001 is equipped with 20mm lug width. This is a specific measurement for this women's model; to verify it, remove the original bracelet and measure the distance between the two lateral pins with a digital caliper.

Which strap should I choose for the Constellation 131.25.28.60.52.001?

For the Constellation in Sedna Gold and steel, we recommend black alligator or cognac brown leather (natural leather tone), smooth calf in dark blue, or bordeaux-brown shell cordovan for those who appreciate the evolution of patina over time. We do not recommend rubber, as it unbalances the refined aesthetics of the model. Every strap must have compatible 20mm lugs.

How do I change the strap on my Omega Constellation 131.25.28.60.52.001?

Remove the bracelet using a spring bar tool. Position the tool under the lateral pin, press gently to release the internal spring, and extract the pin. Repeat on the other side, then insert the pins of the new strap into the lugs, ensuring the spring clicks into position.

Can I use an aftermarket strap on this Omega?

Yes, provided the strap is equipped with compatible 20mm lugs. Artisanal straps from milanostraps.it are specifically crafted for this measurement and fit perfectly with the Constellation 131.25.28.60.52.001 case.

How long does a leather strap last on a luxury watch like the Constellation?

A quality leather strap (alligator, shell cordovan, calf) typically lasts 3-5 years of daily wear, depending on the leather and care. Casati Milano straps include an 18-month warranty and can be subjected to periodic maintenance to extend their life. The evolution of patina is a natural part of leather aging.
