F.P. Journe Octa UTC Platinum 40mm

Produced between 2011 and 2018, the F.P. Journe Octa UTC (Ref. UTC) is a masterful representation of haute horlogerie designed to elegantly display Coordinated Universal Time. Housed in a refined 40mm case crafted from either platinum or 18K 6N gold, the watch features a visually striking, multi-layered dial. The display includes off-center hours and minutes, a large date window, a power reserve indicator at 9 o'clock, and a beautifully detailed earth dial featuring a laser-engraved and painted world map on a sapphire disc. Its clever UTC complication allows the wearer to set their home time zone by mechanically rotating the globe via a secured pusher at 4 o'clock, effortlessly synchronizing the gold hand while accounting for summer and winter daylight saving times through dedicated +1 and -1 indicators.

At the heart of the Octa UTC beats the exceptional in-house automatic Calibre 1300.3, a mechanical marvel meticulously crafted from solid 18K rose gold. This sophisticated movement operates at a frequency of 21,600 vibrations per hour (3 Hz) and boasts a remarkable power reserve of roughly 160 hours, offering over five days of guaranteed chronometric performance from a large-capacity mainspring barrel. The automatic winding is highly optimized by an off-center 22K gold guilloché rotor that winds unidirectionally, utilizing an exclusive self-locking ceramic ball bearing system to exploit even the slightest wrist movements. Profoundly decorated with circular Côtes de Genève on the bridges and circular graining on the baseplate, this calibre exemplifies F.P. Journe's unwavering dedication to mechanical precision and artistic craftsmanship.
