Ferdinand Berthoud Chronomètre FB 3SPC.4-1 — Cylindrical Hairspring Chronometry in Black Ceramised Titanium

Ferdinand Berthoud puts the FB 3SPC into black ceramised titanium — only the second non-precious case for the model and the first with a ceramised coating. The COSC-certified calibre FB-SPC keeps its cylindrical hairspring, variable-inertia balance and 72-hour reserve, now with vertical brushing and, for the first time on this line, crown guards.
