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 created the new Octa caliber (1300-3) that uses the slightest movement to automatically wind the
watch. With talent, the watchmaker turns the problem around, and creates a new off centered rotor heavier in 22K gold, that winds
in only one direction with a self-locking ball bearing system. The ceramic balls allow the rotor 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 new calibre retains the characteristics of the classic Octa with: a five day power reserve (120h) and a variable inertia
balance wheel for an optimum yield that offers each model of the Octa line an irreproachable stability. The Octa collection is conceived
for all lifestyles, from the most extreme to the most quiet.
