Frequently asked questions

What is the lug width of the Omega Constellation 131.25.25.60.55.001?

The Omega Constellation with reference 131.25.25.60.55.001 features a 16mm lug width. This measurement is the distance between the two male lugs of the case (the Constellation lugs) and determines which strap or bracelet can be fitted. Measuring the lug width is essential before ordering a replacement strap.

What strap material is best suited for the Constellation 131.25.25.60.55.001?

For this 25mm women's model with mother-of-pearl dial and Sedna Gold-steel case, alligator in dark shades (black, blue) or shell cordovan havana offer the finest aesthetic synergy. Vegetable-tanned calf is ideal for those seeking tactile softness, while rubber provides daytime versatility. The choice depends on usage: elegant for alligator/cordovan, versatile for rubber.

How do you replace the strap on the Omega Constellation 131.25.25.60.55.001?

Changing the strap on the Constellation is straightforward: open the case's lateral lugs with a specific tool (spring bar tool), extracting the pins that hold the bracelet/strap to the lugs. After removal, insert the new strap by snapping the bars into position. For those unfamiliar with the procedure, it is advisable to entrust the operation to an expert to avoid damage.

Can I use an aftermarket non-Omega strap on my 131.25.25.60.55.001?

Yes, absolutely. Any strap with a 16mm lug width is compatible with the Constellation 131.25.25.60.55.001. Artisan straps from Milano Straps are crafted for this specific measurement and offer superior quality, customization (leather, color, initials) and an 18-month warranty through the Casati Milano atelier.

How long does a leather strap last on a daily-worn watch?

A quality leather strap (alligator, shell cordovan) typically lasts 2-4 years with daily use, depending on environmental wear, humidity, and cleaning frequency. The natural patina that develops is part of the charm of leather, but material deterioration near the attachment points is inevitable. Rubber offers greater durability (5-7 years), while canvas (NATO) has an even longer lifespan if kept dry.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
