The OCTA Collection reveals the UTC _ Coordinated Universal Time

Created in the 19th Century, Greenwich Mean Time (GMT) originally referred to solar time at the Royal Observatory in Greenwich, London. Already used by the British navy to calculate their longitude position from the Greenwich meridian, it was introduced in the United Kingdom by the Railway Clearing House in 1847. It was then legally adopted as official time throughout Great Britain in 1880, and then in the entire world for the major part of the 20th Century, before being replaced in 1972 by UTC Universal Time, Coordinated, due to the inconsistency of average solar time.

GMT is usually used in the watchmaking world to designate watches with a second time zone. GMT is based on terrestrial rotation, while UTC on atomic international time. Therefore, the two time measurements are close but not the same. Unlike GMT, UTC offers the current view of time zone division directly linked to the real rotation of the earth, and less variable.

F.P. Journe innovates once again with the presentation of the Octa UTC,a patented system that uses the modern standards of determining time zones in full hours. Mechanically it indicates the different time periods linked with the earth’s geographical positions, indicating summer and winter hour.

On the dial, the local hours are indicated by the blue hands, and linked to the calendar indicating the current geographical time. The red gold hand indicates the home time on 24 hours, represented by the Earth’s 24 time zones.

The mechanical movement with automatic winding is manufactured in 18K
red Gold, like all F.P. Journe -Invenit et Fecit- watch creations. It is
constructed on the 1300.3 calibre, and offers an additional
complication to the Octa line, still in the same calibre dimensions. The
dial features off centre hours, minutes and seconds, a retrograde power
reserve, a large date, and for the first time, a dial with the Earth
divided in time zones. The passing of the months from 28 to 31 days is
done manually.
