Strap for Constellation Quartz 27 Polished Red Gold / Brown Supernova

The lug width of the Constellation 123.50.27.60.63.002 is 18mm. This measurement represents the distance between the two attachment pins of the case and is essential for selecting a compatible strap. It is not possible to use straps of other widths (16mm, 20mm, etc.) as they would not adhere correctly to the lugs.

Cognac or black alligator is the most noble choice for the Constellation 123.50.27.60.63.002. Burgundy shell cordovan represents the option that ages best, developing a patina that evolves in parallel with the rose gold. For everyday versatility, a vegetable-tanned calf leather offers comfort and sophistication without stylistic compromise.

Changing the strap on a Constellation 123.50.27.60.63.002 requires a spring bar tool (a specialized tool for removing elastic pins). Insert the tool into the small groove under the pin, apply light pressure to compress the spring, then extract the pin from the case. Repeat on the other side. To insert the new strap, align the holes with the case lugs and reinsert the pins until they click into place. This is a delicate operation that requires care to avoid scratching the rose gold.

Milano Straps 18mm straps are specifically compatible with your Constellation. For construction quality and aesthetics, we recommend alligator or shell cordovan with hand-stitched seams and rose gold finishing (if available). The Casati Milano atelier also offers custom creations with personally selected leathers, ideal for enhancing your investment in the watch.

Durability depends on the material and usage. An alligator or vegetable-tanned shell cordovan lasts 4-6 years with moderate daily wear. Standard calf leather has a shorter lifespan (2-3 years). Vulcanized rubber resists for 5-7 years. All Milano Straps straps include an 18-month warranty against manufacturing defects. The patina that develops over time is natural and adds character to the strap.
