Strap for Constellation Co-Axial 27 Brushed Red Gold / Diamond / Diamond Wave

The Omega Constellation 123.55.27.20.55.006 has a lug width of 20 millimetres. This measurement represents the internal distance between the two lugs on the case where the strap is attached. It is essential to verify this dimension correctly before ordering an aftermarket strap, as an incorrect measurement would result in mechanical incompatibility.

To enhance the aesthetic and construction characteristics of the 123.55.27.20.55.006, an alligator strap with vegetable tanning in brown, burgundy or cognac tones is recommended. These colour choices maintain harmony with the rose gold case. Alternatively, black calf leather represents a formal solution, while shell cordovan variants create a unique chromatic dialogue with the case material.

Changing the strap on the 123.55.27.20.55.006 requires specific tools, typically a spring bar tool and some manual skill. The procedure involves extracting the lateral pins that connect the original integrated bracelet to the case lugs. We recommend consulting an expert watchmaker to avoid damaging the case. Our partner ateliers can perform the operation safely.

Yes. Since the lug width is 20 millimetres, there is a wide range of compatible aftermarket straps available.

The lifespan of a leather strap depends on the intensity of use, climatic conditions and leather quality. On average, a premium quality alligator or calf strap lasts 5-7 years with regular use. Vegetable tanning develops a natural patina over time, improving aesthetic appearance. Milano Straps provides 18 months of coverage on straps made at the Casati Milano atelier.
