On the FB 3SPC.3-1, the regulating organ becomes the visual center of the entire watch. From the front, side, and back, the COSC-certified caliber FB-SPC stays almost constantly visible beneath a tall domed sapphire crystal, finished in black PVD and sandblasted textures that give the watch a far more technical character. Skeletonized white gold hands cut across the darker movement surface, keeping the display legible. Despite its slim 9.43mm profile, the 42.3mm platinum case is extremely complex to produce. More than 30 hours went into machining and finishing the 57 individual components. Crosshatched crown detailing and screwed lugs keep the watch grounded in utility as much as finishing. This unworn Ferdinand Berthoud Chronomètre FB3 SPC Platinum Watch FB3SPC.3-1 is accompanied by papers and the manufacturer's box.
