Both watches are equipped with Journe’s automatic Caliber 1300.3, with a diameter of 30.8 mm, a frequency of 21,600 vph, and a power reserve of more than five days (120 hours) thanks to the movement’s meter-long mainspring and fast, efficient winding system. The movement has a 15-tooth escapement and an off-center winding rotor. Its bridges have a circular côtes de Genève pattern and its baseplate is partially circular grained. The few steel components in the otherwise solid-gold movement are hand-polished and chamfered, and the wheels are chamfered and circular grained. Both Octa watches have platinum cases and three-position crowns for winding the watch, setting the time and date, and — in the Octa Lune — setting and correcting the moon-phase indication.
The F.P. Journe Octa Réserve dial features central hours and minutes, small seconds at 4:30, large date window at 11:30, and its signature feature, a hand-type power-reserve indicator, at 9 o’clock. Each of these Octa watches is available in a 40-mm or 42-mm case. The Octa Réserve with Havana dial is priced at $44,600.
The F.P. Journe Octa Lune (whose movement has 291 parts to the Octa Reserve’s 277, due to the addition of the moon-phase complication) has its small seconds subdial near 6 o’clock, next to the moon-phase display at 7 o’clock. As on the Octa Reserve, the large date appears on the dial at 11:30 and the power-reserve display at 9 o’clock. The price of the Octa Lune with Havana dial is $44,900. The watches will be available exclusively at F.P. Journe boutiques worldwide.
