The Orient caliber F6N43 is part of the F6N4 family of Orient watch movements. It is a 3-hand self-winding automatic movement with a power reserve indicator at 12:00. Orient makes their calibers in-house in Japan. The F6N43 is an evolution movement with up upgraded power reserve to 50 hours on a full wind. This calibre also includes popular functionality including the ability to manually wind the movement, as well as hacking seconds (Orient refers to this as a second hand halt mechanism).

This movement is found in Orient Star’s Outdoors line of sport watches, released in 2019.


Epson claims that the accuracy of the caliber F6N43 averages between +25 / -15 seconds per day.
