Strap for Constellation Quartz 24 Brushed White Gold / Diamond / MOP

The lug width of the Omega Constellation 123.55.24.60.55.017 is 18mm. This measurement represents the internal space between the case lugs and determines the compatibility of any strap. You can verify it by measuring with a digital caliper the internal distance between the two lugs, from the inner point of one to the inner point of the other.

For a 24mm white gold watch, alligator remains the classic and most harmonious choice: its regular texture and characteristic grain enhance the elegance of the precious metal. Niloticus alligator in black or dark brown creates optimal luminous contrast. Refined alternatives include shell cordovan, which develops a deep patina over time, or calfskin for those seeking greater daily versatility.

To change the strap, you need to remove the current strap from the case lugs. Most Omega straps can be removed using a spring bar tool, which allows you to compress the internal spring and release the strap. It is advisable to work on a soft, flat surface to avoid scratches. The new strap must have a lug width of exactly 18mm to ensure perfect compatibility.

Any strap with an 18mm lug width is compatible with the 123.55.24.60.55.017. High-quality aftermarket straps made from alligator, shell cordovan, calfskin, and Jacquard fabrics represent the most popular choices. It is important to verify that the strap is able to accommodate the lug system (standard lug or integrated lug) of your Omega case.

The lifespan of a leather strap depends on the material, construction quality, and intensity of use. A high-quality alligator or shell cordovan can last 5-8 years with regular use, developing an elegant patina over time. Calfskin, being more delicate, has an average lifespan of 3-5 years. Straps made by Casati Milano come with an 18-month warranty and can be regenerated or replaced over time thanks to custom artisanal construction.
