Frequently asked questions

What is the lug width of the Omega Constellation 131.10.34.20.02.001?

The lug width measures 21mm, a precise dimension that determines strap compatibility. This width maintains the elegant proportions of the 34mm case and was chosen by Omega to ensure visual balance on the wrist.

Which strap material is best suited for the Constellation 131.10.34.20.02.001?

Alligator remains the most coherent choice with the Constellation's DNA: the irregular texture of the scales dialogues perfectly with the houndstooth pattern of the dial. Calf leather follows for everyday wear, and rubber for sports contexts.

How do I change the strap on my Omega Constellation 131.10.34.20.02.001?

Use a flat-blade screwdriver or spring bar tool to remove the spring bars from the sides of the case. Gently extract the spring, remove the old strap, and insert the new one, ensuring the spring positions perfectly in the lugs.

Can I use an aftermarket strap on the Constellation 131.10.34.20.02.001?

Yes, provided the strap has an exact lug width of 21mm. Custom artisanal straps guarantee precise compatibility and allow you to personalize color, material, and finish according to your aesthetic preferences.

How long does a leather strap last on the Constellation 131.10.34.20.02.001?

A quality leather strap (alligator, calf, vegetable tanned) typically lasts 3-5 years with daily wear, depending on frequency of use, ambient humidity, and maintenance. Vegetable tanned leather develops natural patina and can last longer. Artisanal straps from Casati Milano include an 18-month warranty.
