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 ind
