Strap for Mille Miglia Gran Turismo XL Power Control Black / Bracelet

The Chopard Classic Racing 158457-3001 features a lug width of 23 millimetres. This measurement represents the distance between the strap attachment pins on the case and must be measured precisely using calliper gauges. It is essential to verify this measurement before ordering a strap to avoid incompatibility issues. At 23mm, this is a niche width requiring specialised watch accessory suppliers.

For a sporting chronograph like the Classic Racing, we recommend genuine alligator leather, shell cordovan or superior quality calf leather preferably vegetable-tanned. These materials offer durability spanning multiple years and develop a patina that narrates the passage of time, perfectly aligned with the segnatempo's vintage aesthetic. Valid alternatives include cotton-nylon NATO straps for practicality or vulcanised rubber for optimal grip during driving.

To replace the strap, remove the timepiece and position it on a soft surface. Locate the attachment pins on either side of the case (23mm apart). Use a dedicated tool to remove the pins, extracting the old strap. Position the new strap and re-insert the pins into the case attachments, ensuring they are securely fastened. If you lack experience, consult a professional to avoid damage.

Yes, provided the aftermarket strap is designed precisely for the 23-millimetre lug width. Many aftermarket straps do not respect this specific width, therefore it is essential to verify the technical specifications before purchase. Specialised artisanal strap suppliers offer bespoke solutions guaranteeing perfect compatibility and material quality.

The lifespan of a leather strap depends on material quality, tanning type and intensity of use. A strap crafted in superior-grade alligator or shell cordovan, preferably vegetable-tanned, can last 5 to 10 years with proper maintenance. Premium leather naturally develops a patina that increases aesthetic value over time. Protect the strap from excessive moisture and direct sunlight exposure to prolong durability.
