When faced with a timepiece that requires 11,000 hours of dedicated labour, one cannot help but question the justification for such an investment. The answer lies not in the watch itself, but in what its creation preserves: knowledge that cannot be digitised, skills that take years to acquire, and traditions that define excellence through difficulty rather than efficiency. Chronométrie Ferdinand Berthoud's Naissance d'une Montre 3 is the result of a six-year collaboration between the manufacture and Chopard artisans, representing the third chapter of an initiative launched to safeguard endangered watchmaking crafts. This is no marketing exercise. The watch provides documentary proof that contemporary tolerances and historical techniques can coexist, that COSC chronometer certification can be achieved using a Guillaume balance and fusée-and-chain, and that 18th-century regulating systems can operate with precision in 2026.
