Frequently asked questions

What is the exact lug width of the Omega Constellation 123.20.24.60.02.001?

The lug width of this model measures exactly 20 millimeters. This dimension represents the internal distance between the two lateral lugs of the case where the strap is suspended. It is essential to verify this measurement before purchasing an aftermarket strap to avoid incompatibility.

What strap material is recommended for the 24mm Omega Constellation in rose gold and steel?

For this model, alligator represents the most coherent choice from an aesthetic and qualitative standpoint. A dark blue or deep brown alligator strap amplifies the chronometric nature of the watch. Alternatively, vegetable-tanned calf leather offers sober elegance and develops natural patina over time; structured rubber ensures contemporary versatility.

How do you correctly measure the lug width of a watch?

Lug width measurement should be performed using a digital caliper or a precise ruler. Position the measuring instrument between the centers of the two lateral lugs of the case – not on the external part. The measurement must be taken from the inside, as this is the actual distance available for the strap. In the case of your Constellation, the result should be 20mm.

Is a generic 20mm strap compatible with the Omega Constellation 123.20.24.60.02.001?

Not necessarily. Although the lug width is 20mm, compatibility also depends on the curvature of the lugs and the type of attachments. Milano Straps verifies every strap before shipment to guarantee perfect insertion into the specific attachments of this Constellation model.

How long does a leather strap last on a wrist watch like this Constellation?

A quality leather strap, if properly cared for, lasts an average of 2-4 years with regular use. Factors that influence longevity are: frequency of use, exposure to moisture and sun, type of tanning and quality of stitching. Straps made by Casati Milano include an 18-month warranty and are constructed with materials and stitching designed to guarantee superior durability.
