Chronomètre FB 1L
Available in two ten-piece Two Faces of the
Moon limited editions, this set of deeply
technical 44mm watches indicate the age of
the Moon and its phases as determined by an
extremely precise movement regulated using a
tourbillon with fusee-and-chain (constant-force)
transmission.
One model, showing the near side of the
Moon (left), is made with a white gold case with
black ceramic lugs; the other, indicating far
side moon phases, is darker, made using grey
ceramic titanium and sandblasted white gold.
The displays show hours and minutes on a
dedicated subdial at 12 o’clock, seconds in the
center (driven directly from the tourbillon) and
the fifty-three-hour power reserve on the back
of the movement.
A large hand at the lower left side of the
dial indicates the age and phases of the moon
in a continuous back and forth movement on
an unusual plate marking the orb’s fourteen-
day monthly full moon to new moon session.
Combined here, for the first time, are a
chronometer and an indicator of the age
(waxing or waning) and phases of the moon, all
within the same watch. Also new is the
selector switch at the side of the case between 4
and 5 o’clock that enables the wearer to choose
between two positions, L and H, to set the age of
the moon or the time.
This tour-de-force features four patents.
Prices: $278,500 (white gold) and $262,500
(grey titanium).
