THE DIAL
Round markers, warm contrast.
Grey at the centre deepens towards the dial edge. The warm hands and round luminous markers stand out against that darker surround, while the day-date window at three keeps the design practical.
Luminous hands and hour markers keep the main time display visible in low light after exposure to light. Their brightness fades gradually; the calendar is not illuminated.
TIMEKEEPING
The mechanism behind the dial.
Orient calibre F6922 combines automatic and manual winding with a seconds-stop mechanism for time setting. Its day-date display gives mechanical timekeeping a practical daily reference. Follow the supplied instructions when winding or adjusting the calendar.
