Strap for Constellation Quartz 24 Brushed Red Gold / Diamond / MOP Supernova

The lug width of the Omega Constellation 123.55.24.60.55.001 is 16mm. This is the internal distance between the two lugs of the 24mm case. To verify it, measure with a digital caliper the space between the small metal supports that anchor the strap to the case. Any compatible strap must have exactly 16mm width.

For the Omega Constellation 123.55.24.60.55.001 in rose gold we recommend an alligator strap in dark shades (burgundy, brown, black) or a vegetable-tanned calf leather in cognac color. Alligator is the most refined choice: its micro-structured grain does not compete with the case. Calf leather develops a natural patina over time. Both respect the elegance of rose gold and the compact 24mm proportion. Avoid synthetics and cool tones.

To change the strap on your 123.55.24.60.55.001, proceed as follows: 1) Position the watch on a soft surface (linen cloth). 2) Use a dedicated tool (spring bar tool or special attachment tool) to gently press the ends of the lug downward, releasing the spring bars. 3) Remove the old strap while holding the bars steady. 4) Insert the new strap, ensuring that the spring bars are perfectly aligned in the grooves. If you are uncertain, consult a certified watchmaker.

Yes, the 123.55.24.60.55.001 accepts any aftermarket strap with a 16mm lug width. The case is equipped with standard, non-proprietary lugs, so you have absolute freedom in choosing the brand and material. We recommend selecting straps of certified quality (vegetable-tanned leather or genuine alligator) to preserve your watch's value and guarantee durability of at least a decade.

A high-quality leather strap (alligator or vegetable-tanned calf) on a 24mm Omega Constellation has an average lifespan of 5-8 years with daily use, extendable to 10-12 years with careful maintenance and storage. Durability depends on exposure to water, perspiration, UV rays, and frequency of use. Alligator resists humidity better than calf leather. We recommend drying the watch after water contact and rotating straps to distribute wear. A well-maintained strap can last over a decade.
