Issued in an exclusive five-piece limited edition, the “Oeuvre d’Or” collection pays tribute to its principal source of inspiration, the astronomical pocket watch No. 3 from Ferdinand Berthoud. Its main components are adorned with original decorations: while the dial is finely crafted to obtain an aged patina, the half bridges of the movement also highlight the know-how of the Manufacture’s engravers with their hand-made “pyramid” motif decoration. Both are entirely crafted in 18-carat rose gold and match the octagonal case made of the same precious metal and housing the tourbillon movement with fusee-and-chain transmission system, directly inspired by Ferdinand Berthoud’s creations from the 18th century. 



The patinated dial of FB 1 – Oeuvre d’Or is created using a combination of engraving techniques that require great manual dexterity. First of all, the gold is finely grained with a graver. The surface is then crafted at length using a tool called a "rocker", enabling the light to glide across the dial to the rhythm of the shimmering reflections of the moiré effect thus created. Finally, the dial is hand-engraved and then subtly coloured to perfect the overall legibility.


The FB 1 – Oeuvre d’Or collection features a "pyramid" motif decoration adorning the entire surface of its three half-bridges, an authentic artisanal feat demonstrating the know-how of the Manufacture’s engravers. The material is cut free-hand with flawless precision and regularity using a graver.


The FB 1 collection of Chronométrie Ferdinand Berthoud pays tribute to this work and to the movements that pioneered chronometric precision. Its case is inspired by Ferdinand Berthoud's marine chronometers, in particular their gimbal suspension that served to maintain on-board chronometers in a permanently horizontal position.
