Strap for Constellation Quartz 24 Polished Red Gold / Supernova / Snow

The Omega Constellation 123.55.24.60.55.013 is equipped with a lug width of 12mm. This measurement is the critical parameter for identifying compatible straps: it must be measured between the inner shoulders of the pins that hold the strap. An incorrect measurement carries the risk of incompatibility, so we recommend using a digital caliper for precise verification.

For a Constellation in rose gold, the most suitable materials are alligator in cognac or burgundy tones, aged shell cordovan in caramel, and vegetable-tanned calf leather in Tuscan tan shades. These choices respect the warm color temperature of rose gold. We advise against cold-toned materials (grey calf) or graphic patterns that conflict with the jewelled elegance of the model.

The strap is replaced by extracting the pins from the lugs on the case. Use a dedicated tool (spring bar tool) to push the pin and release it, taking care to maintain balance to avoid dropping the component. Position the new strap, align its lug width with the case holes, and reinsert the pin until it clicks into place. If you are not experienced, Casati Milano can provide a strap-change service by appointment.

Yes, 12mm aftermarket straps are fully compatible with the 123.55.24.60.55.013. Lug width is the universal compatibility parameter. However, we recommend verifying construction quality and materials to ensure longevity. Milano Straps offers premium leather 12mm straps, customizable according to your aesthetic and functional preferences.

The lifespan of a leather strap depends on frequency of use, the material chosen, and maintenance. Quality alligator and shell cordovan can last 3-5 years with regular use, while vegetable-tanned calf has slightly shorter cycles (2-3 years). Constant exposure to sweat, humidity, and UV rays accelerates aging. Casati Milano straps include an 18-month warranty and can be regenerated through a reconditioning service.
