Chopard
Classic Racing 168570-3002— lug 20mm

The lug width of the Chopard Classic Racing 168570-3002 is precisely 20mm. This measurement is determined by the distance between the lugs pins connecting the strap to the case, measured at the internal base of the lugs. To verify compatibility, measure the space between the lugs with a digital calliper, ensuring you include the thickness of the strap material in your final assessment.

For the 168570-3002, we primarily recommend a stamped alligator strap or vegetable-tanned leather, which maintain the racing aesthetic and develop natural patina over time. Alternatively, FKM rubber or black NATO fabric are excellent choices for daily wear. We advise against synthetic glossy leather or straps with gold detailing, which would conflict with the model's austere aesthetic.

To change the strap, obtain a quality spring bar removal tool. Position the watch with the lugs facing upward, insert the tool's thin end into the lateral hole of the pin, gently push to release the spring, and extract the old strap. Insert the new 20mm strap pins into the lugs, ensuring they fully engage. If you lack the specialist tool, a professional watchmaker can complete the operation in minutes at modest cost.

Yes, it is entirely possible and recommended. Quality aftermarket straps (particularly those handcrafted in natural leather) offer greater aesthetic freedom and durability compared to standard straps. The critical factor is verifying that the lug width is exactly 20mm and that material thickness does not exceed 4.5mm, to avoid friction with the lugs. Milanostraps provides a specific selection of compatible straps for this measurement.

A quality leather strap (alligator, calf, shell cordovan) subjected to moderate use and conscious maintenance lasts an average of 4-6 years. Durability depends on usage frequency, climatic conditions (humidity and sun accelerate deterioration), and routine care (avoid prolonged immersion, dry promptly if wet). FKM rubber straps have superior longevity, up to 8-10 years. Vegetable tanning slows ageing due to its natural composition. Visible ageing does not indicate failure; the patina adds narrative value to the strap.
