F.P.Journe Automatique Lune

In 2001, F.P.Journe presented the Octa – a collection of mechanical wristwatch chronometers with automatic winding systems offering a very long power reserve, all of which have the same case thickness regardless of the complication.

The new Automatique Lune presents a larger date (4.7 x 2.6 mm) and a moon in sapphire also enlarged for an optimal readability.

The mechanical movement with automatic winding in 18K rose Gold provides a power reserve of 160 hours. It is winded by the mono directional off center 22K 6N Gold rotor which uses any slightest movement of the wrist for an optimal winding of the watch and an unequalled efficiency.

The variable inertia balance wheel provides an optimum yield for the Automatique Lune as well as for all models of the Octa Collection with an irreproachable stability.

The Automatique Lune is available with a case in 40 or 42 mm. in Platinum or in 6N Gold, with a guilloche clous de Paris Silver dial, on leather strap or Platinum or 6N Gold bracelet, in the F.P.Journe Boutiques and Espaces as well as from authorized retailers.
