Ferdinand Berthoud’s Chronomètre FB 3SPC has always been the quietly technical member of the house’s modern watchmaking family.
Now it arrives in a sharper, more contemporary form, with a black ceramised titanium case, new crown guards and a textile strap that shifts the watch closer to daily-wear territory without diluting its horological seriousness.
For a brand built around precision chronometry rather than volume, this is a meaningful update.
At a glance
- Ferdinand Berthoud has introduced the Chronomètre FB 3SPC.4-1 in black ceramised titanium.
- The watch retains the calibre FB-SPC with cylindrical hairspring, variable-inertia balance and COSC chronometer certification.
- Price is upon request, with a black textile strap as standard and additional strap options available on request.
A darker case for the FB 3 family
The FB 3SPC.4-1 keeps the familiar 42.3mm case diameter and slim 9.43mm height, but the mood is entirely different.
Black ceramised titanium gives the watch a matte, sandblasted appearance while preserving titanium’s lightness and adding improved scratch resistance.
It’s also the first FB 3 reference to feature crown guards, which flank the large 8.5mm crown and give the case a more architectural, slightly sportier profile.
The water-resistance remains 30 metres, so this isn’t being recast as a sports watch in the conventional sense.
Instead, Ferdinand Berthoud has used material, silhouette and strap choice to make a highly technical chronometer feel less formal.
The case still carries the details that define the collection, including screwed lugs, domed sapphire crystals front and back, and a rectangular sapphire porthole on the left flank.
That side window is more than decoration, as it offers a direct view of the cylindrical balance spring at work.
The cylindrical hairspring remains the main event
The FB 3 collection takes inspiration from a late-18th-century decimal pocket watch made by Louis Berthoud, nephew of Ferdinand Berthoud.
Its defining mechanical idea is the cylindrical hairspring, a form historically associated with marine chronometers and precision timekeeping.
Unlike a flat hairspring, a cylindrical or helical spring expands and contracts around its central axis with greater symmetry.
In wristwatch form, that geometry is extremely difficult to execute at scale.
Ferdinand Berthoud’s watchmakers paired the hand-shaped cylindrical spring with a variable-inertia balance, producing a calibre that holds COSC chronometer certification.
The result is a watch that doesn’t rely on a tourbillon or fusée-and-chain system to make its chronometric point.
It chooses a rarer path, bringing a historic regulating solution into a contemporary wristwatch architecture.
An open architecture with serious hand-finishing
The dial side is built around a black sandblasted German silver mainplate, with time indicated by a peripheral black-varnished brass ring carrying grey numerals.
A matching small seconds display sits at 6 o’clock, while the power reserve indicator is placed at 2:30.
The white gold hour and minute hands are open-tipped, skeletonised and sandblasted, keeping the emphasis on the mechanics rather than surface ornament.
At 9 o’clock, the regulating organ is staged beneath three separate bridges.
The upper bridge secures the cylindrical balance spring, the middle bridge holds the anchor, and the lower bridge carries the escapement wheel.
The movement finishing is deliberately visible and deeply traditional.
The calibre includes 102 exterior angles and 15 inward angles, all finished by hand, while the six visible dial-side bridges receive a vertical satin finish that demands precise alignment across separate components.
Turn the watch over and the exhibition caseback reveals the other side of the calibre FB-SPC, with ten individual bridges and eight decorative finishing techniques across the movement.
