Strap for Grand Prix de Monaco Historique Chrono Strap

The lug width of the Chopard Classic Racing 168570-3001 is 20mm. This measurement defines the internal spacing between the spring bars that anchor the strap to the case. Measure the distance between the internal notches of the lugs to verify: it must be exactly 20mm for the strap to fit without play.

For the Classic Racing 168570-3001, we recommend authentic alligator with vegetable tanning for motorsport elegance, or technical-fabric NATO in black or blue for daily sportiness. On steel cases, black alligator amplifies formality; on titanium, a navy NATO conveys contemporary character. Vintage cognac calf is the versatile alternative combining warmth and durability without intensive maintenance.

Gently extract the spring bars from the lugs using a spring bar tool or blunt-edged implement. Insert the new 20mm strap by aligning the spring bars into the lug holes and press until you hear a click. Verify the spring bar is fully seated before wearing the watch.

Any strap with a 20mm lug width is compatible. Online you will find options in alligator (black, cognac, cream), vegetable-tanned calf, NATO fabric, FKM rubber, and shell cordovan. Ensure the supplied spring bars match the diameter of your original bars.

A quality leather strap (alligator or calf) lasts 3-5 years of regular daily wear, varying by climate, skin moisture, and maintenance. Vegetable-tanned leather ages nobly, acquiring patina and character. Rubber lasts 5-7 years before losing elasticity. Skin oils accelerate leather degradation; clean periodically with a dry soft cloth.
