Chopard
Classic Racing 168992-3031— lug 20mm

The Chopard Classic Racing 168992-3031 features a 20mm lug width. This specific measurement is the result of Chopard's proportional calculation to respect the historical geometries of the Classic Racing line. It is essential not to confuse this measurement with the more common 22mm used in many contemporary chronographs, as an incompatible strap will not fit correctly onto the watch's spring bars.

The best strap depends on the intended use. For formal elegance, we recommend black or brown laminated alligator: the regular texture perfectly harmonises with the dark dial and polished case. For durability and patina development over time, vegetable-tanned calf leather in dark brown tones offers superior robustness and dignified ageing. For intensive sports use, an FKM rubber or NATO deployante maintains fidelity to the motorsport heritage of the line.

Strap removal requires extraction of the two spring bars connecting the lugs to the case. Use a dedicated tool (spring bar tool) to press towards the centre of the lug, freeing the pins from their housing. Once freed, the strap detaches easily. Installing the new strap follows the reverse procedure: position the pins in the attachment holes and ensure the strap is aligned symmetrically. If you lack experience, we recommend assistance from a certified watch service centre.

Absolutely. High-quality aftermarket straps, provided they are manufactured to the correct lug width (20mm), are perfectly compatible with the 168992-3031. Many owners choose to alternate straps in different finishes and materials to adapt the watch to different contexts. It is important to verify that the aftermarket strap is produced by specialised manufacturers that guarantee precision and the use of noble leathers or technical materials equivalent in quality to the watch itself.

The lifespan of a leather strap depends on multiple factors: frequency of use, exposure to moisture and sunlight, type of tanning and quality of manufacturing. A well-made alligator or calf leather strap in vegetable tanning can maintain integrity and aesthetics for 5-7 years of regular use. Leather ages naturally, developing a patina that many collectors appreciate. Prolonged sun exposure accelerates surface oxidation, whilst moisture can cause mildew if the strap is not allowed to dry properly. Regular maintenance and alternating use between multiple straps significantly extends the lifespan of any individual strap.
