Strap for Constellation Co-Axial 31 Red Gold / Diamond / MOP Supernova

The lug width is 20mm. This measurement represents the distance between the upper and lower lugs of the case. It is essential to measure it precisely using a digital caliper perpendicular to the lugs, as any discrepancy compromises the visual fit of the strap to the case.

Alligator and shell cordovan represent the most refined choices, as they develop a patina over time in harmony with red gold. Vegetable-tanned calf offers artisanal authenticity, while NATO fabrics provide contemporary versatility. The choice depends on usage: formal wear requires noble leathers, sports wear prefers rubber or NATO.

Remove the original strap by extracting the lateral pins with an appropriate tool (spring bar tool). Position the new strap, ensuring the pins enter the holes smoothly.

Yes, provided it has a lug width of 20mm. Custom artisanal straps fit perfectly, as they are built respecting the case specifications. Standard commercial straps must be verified: some manufacturers offer adjustable lengths through additional loops.

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts on average 2-4 years with daily use, depending on care. Constant exposure to sweat, sunlight, and humidity accelerates aging. Casati Milano straps include an 18-month warranty and are restorable: professional reconditioning extends the useful life by another 2-3 years.
