F.P. Journe Octa UTC

F.P. Journe Octa UTC

F.P.Journe’s Octa UTC is a GMT or two time zone watch that incorporates a patented system to indicate the second time zone using both a traditional second hour hand and an unconventional graphical representation of the Earth showing the 24 standard, full-hour time zones and taking into account summer and winter time.

On the dial, the blue hour and minute hands (and the date) indicate the owner’s local time. Once the local time is set, the owner positions the second geographical region – indicated by the colorful globe – on “0″ for winter hour. The gold hand, which makes one complete rotation every 24 hours, automatically positions itself at the corresponding time for this region. The +1 /-1 graduation positions the specific region for summer hour linked to the geographical location of the user, depending if it is positioned east or west of the chosen zone.

The Octa UTC is available in platinum or 18K red gold, and in 38 or 40mm diameters.

The automatic-winding movement is manufactured in 18K rose gold, as are all F.P.Journe creations. It is constructed on the 1300.3 caliber without changing the caliber’s dimensions. Adjusting the date from 28 to 31 is done manually. All Octa timepieces offer a 5 day power reserve.
