Two sapphire crystal windows on the case sides reveal the intricate operation of the fusée-chain system — a direct tribute to Berthoud’s 18th-century marine chronometers. The dark grey sandblasted dial presents a frosted texture, enhanced by a circular satin-brushed minute track. A partially openworked sector exposes the golden gear train between 3 and 6 o’clock. A power-reserve indicator is positioned at 9 o’clock, while skeletonized hands and a blue CVD seconds hand provide crisp legibility. Every detail reinforces the technical depth of the Ferdinand Berthoud Chronometre FB 1RES.4. Inside beats the FB-RES.FC manual-winding movement, certified by COSC and operating at 18,000 vph. Comprising nearly 1,200 components, the movement features the signature fusée-chain transmission — using a cone-shaped pulley to deliver constant torque and exceptional precision. Each component is hand-finished, maintaining the traditional haute horlogerie standards of the Ferdinand Berthoud manufacture. Paired with a black alligator leather strap, the Ferdinand Berthoud Chronometre FB 1RES.4 is limited to only 38 pieces worldwide, making it one of the rarest fusée-chain creations in modern watchmaking.
