Ferdinand Berthoud Chronomètre FB 3SPC 161307-1001 Watch

The Chronomètre FB 3SPC is inspired by Louis Berthoud’s rare 1793 decimal watch No. 26, reflected in its elegant 18ct white gold case echoing early 19th-century pocket watches. Each watch is crafted start to finish by a single watchmaker, ensuring exceptional detail. Its eggshell-toned, sandblasted brass dial adds timeless sophistication, while the 57-part case undergoes over 30 hours of meticulous hand-finishing and polishing. Ferdinand Berthoud uses a 6.7x magnification finishing process to detect even the smallest imperfections. Every component is carefully examined under this loupe to ensure flawless finishing, especially on sensitive untreated nickel silver. At 9 o’clock, the dial reveals the regulating organs, the balance wheel, pallet lever, and escape wheel, visible through the open dial and a water-resistant side porthole. This design offers a full view of the escapement’s motion and the rhythmic pulse of the rare cylindrical balance-spring over its three-day power reserve. Powering the watch is Calibre FB-SPC, a COSC-certified movement featuring a rare cylindrical balance-spring. A central mainplate supports bridges inspired by Berthoud’s original work. Warm 18ct gold components complete the blend of technical mastery and historical homage, making the Chronomètre FB 3SPC a truly exceptional collector’s timepiece.
