Strap for Constellation Quartz 27 Brushed Red Gold / Diamond / Silver Omega

The Omega Constellation 123.55.27.60.52.001 has a lug width of 18mm. This technical parameter represents the distance between the two lugs of the case where the strap is fitted. It is essential to measure this dimension correctly to ensure complete strap compatibility. An incorrect measurement results in straps that are too wide or too narrow.

The choice depends on your personal priorities. For formal elegance, we recommend black or dark brown alligator, which creates a sophisticated contrast with the rose gold case. For daily comfort, aniline calf leather in cognac or taupe tones offers a soft hand and evolving patina. If you prefer sustainability and natural aging, vegetable tanning guarantees ecological material with authentic character. Any choice must respect the 18mm lug width.

The strap on this model is fitted to the case lugs via spring bars. For replacement: remove the original strap by gently pushing the locking pins from one side with a dedicated tool (spring bar tool). Align the holes of the new strap with the case lugs and reinsert the pins until they click into place. We recommend having this operation performed by an expert to avoid damage to the case.

The durability of a leather strap depends on the material, frequency of use, and maintenance. A quality alligator strap, used daily, maintains structural functionality for 4-6 years, while the aesthetics improve with natural patina. Aniline calf leather has similar durability but shows more visible signs of wear. Vegetable-tanned leather, if properly cared for, can last 6-8 years or more. Casati Milano atelier provides an 18-month warranty on construction; subsequent wear is natural and does not constitute a defect.
