Always taking into account the notes and observations concerning his watches, François-
Paul Journe states: “I realized that one of my friend’s Octa was never completely wound because
he works on a computer and his hand doesn’t move enough.”
From this observation he creates the new Octa calibre (1300-3) that uses the slightest
movement to automatically wind the watch. With talent, the watchmaker turns the problem
around, and creates a new system that winds in one direction, only with a self-locking ball bearing
system. The ceramic balls allow the off-centred rotor in 22 carats red Gold to move in one direction
and block it in the other. This way, every infinitesimal movement is maximally exploited for an
optimized winding of the watch.
The calibre retains the characteristics of the classic Octa with: a 160-hour power reserve
and a variable inertia balance wheel for an optimum yield that offers each model of the Octa line
an irreproachable stability.
