Ferdinand Berthoud FB1L Far Side of the Moon An intriguing blend of astronomy and chronometry, Ferdinand Berthoud’s FB1L Far Side of the Moon offers an innovative and unique display of both the age and phases of the moon. It is equipped with a tourbillon with constant-force regulation thanks to a fusée-and-chain transmission, which is part of the brand’s identity.
There are two existing patents in this watch, including the suspended fusée differential winding system and the tourbillon, which has a direct-drive second hand. There is a patent-pending for the cam and spindle at 9 o’clock, where a hand displays the age of the moon in days. The small globe at 4 o’clock displays the current moon phase.
The FB-T.FC.L caliber is so complicated that it consists of 1,240 parts and ensures astronomical precision for 577 years before it will deviate by a single day. The 44mm watch is a COSC-certified chronometer and, unsurprisingly, just 10 pieces will be made of this special version.
Price: $262,000 in ceramized titanium and 18K white gold
