it was in 1990 that the dual-time calibre was
launched in the marketplace, the first wristwatch
powered by a single movement capable of displaying
two time zones simultaneously.
the power required by an automatic watch to wind
it and maintain its functions is produced by wrist
movements.
the kinetic energy is supplied by an oscillating
weight with 21-carat gold segment and is transmitted
to the mainspring via a wheel train.
By winding gradually around the barrel arbour, the
spring accumulates this energy which is then passed
back to the watch movement wheel train.
the time to reach the maximum power reserve
varies according the temperament and activity of
the wearer.
to prevent overtensioning of the mainspring, it is
released at the appropriate moment by a sophisticated
system which allows it to slip inside the barrel drum.
