FAQ

What is the <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Omega Constellation 111.25.36.20.52.001?

The Omega Constellation 111.25.36.20.52.001 is fitted with a 20mm lug width. This width is standard for many vintage and modern Constellation models, and is compatible with a wide catalogue of artisanal straps.

What strap material is recommended for this Constellation?

For the Constellation 111.25.36.20.52.001 in rose gold and steel, we recommend calfskin leather, alligator, or shell cordovan. Alligator enhances the sporty-dress elegance, while vegetable-tanned calfskin develops visible patina over time. Natural materials balance its two-tone character.

How is the <a href="/pages/termine-glossario/misura-ansa">lug width</a> of a watch measured?

Lug width is the distance between the two case lugs in millimetres. For the 111.25.36.20.52.001 it is 20mm: measure the internal space between the lugs where the strap is inserted. This dimension determines strap compatibility.

Can I fit an aftermarket strap on this Omega Constellation?

Yes. The Omega Constellation 111.25.36.20.52.001 accepts any strap with 20mm lug width. Aftermarket straps offer aesthetic customization, texture and leather finishing variations, as well as styling alternatives to the original bracelet, while maintaining full mechanical compatibility.

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

A quality leather strap, if properly cared for, has an average lifespan of 18-24 months with daily wear. Materials such as shell cordovan and alligator age naturally, developing visible patina and grain, extending aesthetic durability. Milano Straps warranty covers 18 months.
