Strap for Mille Miglia GTS Power Control Israel 70th Anniversary

The lug width of the Chopard Classic Racing 168566-3009 is 21mm. This measurement, also known as ansa width, is the distance between the two metal pins that support the strap. It is the fundamental technical specification for ensuring compatibility with aftermarket straps. To verify it, measure from inside to inside between the pins using a digital calliper.

The ideal strap depends on your lifestyle and aesthetic preferences. For sartorial elegance, we recommend alligator leather with vegetable tanning (cognac or mahogany brown). For daily sporting use, vegetable-tanned calf leather offers versatility. For a pure racing interpretation, technical fibre NATO straps or vulcanised rubber amplify the motorsport DNA. The Casati Milano atelier personalises every choice based on your wrist.

Strap changing is done through the metal pins that pass through the lugs of the case. Use a spring bar tool to gently push the pin from one side, freeing the old strap. Position the new strap and reinsert the pin, ensuring it is fully locked on both sides. If you are not experienced, entrust the task to a professional watchmaker.

Yes, any strap designed for a 21mm lug width is completely compatible with the 168566-3009. Milano Straps offers a collection of handcrafted 21mm straps customisable in leather (alligator, calf), NATO and rubber, ready for shipment. The Casati Milano atelier also creates bespoke versions with personal selection of leathers.

Durability depends on the material, tanning method and use. An alligator or vegetable-tanned calf strap, with proper care, lasts 3-5 years of moderate daily use. Avoid prolonged exposure to water and perspiration, and periodically apply a leather balm. The guarantee provided by Milano Straps and Casati Milano covers manufacturing defects for 18 months, after which wear is natural and the strap can be replaced.
