Frequently asked questions

What is the lug width of the Omega Constellation 131.58.29.20.53.001?

The lug width of this model is 18 millimeters, corresponding to the distance between the upper holes of the bracelet. This width, proportional to the 29mm diameter, allows the use of specific artisanal straps without the need for adapters.

Which strap material is most suitable for the 29mm Constellation in yellow gold?

Alligator remains the preferred choice for this Constellation: the natural texture with regular dimples perfectly complements the refinement of yellow gold and ensures durability in daily wear. Alternatively, vegetable-tanned calf leather offers a patina that ages beautifully over time.

How do you change the strap on an Omega Constellation 131.58.29.20.53.001?

The Omega Constellation 29mm features an integrated, non-removable bracelet, so an alternative strap must be installed via spring bars on a two-piece strap with lugs specific to the 18mm width. It is recommended to have the operation performed by a professional watchmaker to avoid damage to the yellow gold lugs.

Are there aftermarket straps compatible with the Constellation 131.58.29.20.53.001?

Yes, numerous artisanal straps in 18mm size are compatible with this Constellation. On milanostraps.it you will find a curated selection of customizable leather options in various colors and stitching finishes, ready for shipment or made to order at the Casati Milano atelier.

How long does a leather strap last on an Omega Constellation watch?

The lifespan of a leather strap depends on the material and daily use. Quality alligator typically lasts 3-4 years of regular wear; vegetable-tanned calf leather can last 2-3 years. Artisanal straps from Casati Milano include an 18-month warranty and can be restored or have worn elements such as the deployant replaced.
