Chronomètre Ferdinand Berthoud FB 1 “Night Star”, Unique Piece for the “Only Watch” 2019 Auction

Chronométrie Ferdinand Berthoud is taking part in the “Only Watch” charity auction for the first time. For the eighth edition of this event, it is donating a unique piece created especially for this occasion: the Chronomètre FB 1 “Night Star”. It will be sold by Christie’s in Geneva on 9th November 2019 to support funding to fight Duchenne muscular dystrophy, a form of muscle degeneration that is currently incurable.

The FB 1 “Night Star” model has a sandblasted anthracite-ceramised titanium case. This treatment renders titanium four times more resistant than traditional titanium, while giving it a distinctive appearance.

A play on colours is at the heart of the design of this one-of-a-kind model. It is the first ever designed by Chronométrie Ferdinand Berthoud to feature hands and numerals equipped with SuperLumiNova. This luminescent material, deliberately chosen in white, contrasts with the dark tones of the exterior, evoking the gleam of the stars in the night sky. Historically, stars were navigators’ reference points for their position on the oceans, thus recalling the ancestry of the FB 1 collection, designed in the wake of Ferdinand Berthoud’s work on calculating longitude at sea.

Symbolically, white Super-LumiNova evokes the ray of hope that inspires the fight against Duchenne muscular dystrophy.

The black ceramic crown inlay matches the frosted black dial, a finish found on the Manufacture’s most recent models. On the case-back side, the Chronomètre FB 1 “Night Star” Chronometer features three bevelled sapphire semi-bridges, providing a chance to admire the entire black rhodium-plated movement with fusée-and-chain transmission and direct-drive seconds.
