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 off centered heavier rotor, that winds in one direction only 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 opti-
mized 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 new “lineSport” is composed of a collection of ultra light watches entirely made in
Titanium and Aluminium: specifically conceived for a proficient sportive activity. The Aluminium
movement of each watch of the “lineSport” retains the exceptional properties of the exclusive
F.P. Journe calibres.
