Orient power reserve
Orient Power Reserve features Orient watches with power reserve meter to indicate remaining stored energy to operate the watch. The power reserve indicator displayed on the watch with automatic-winding movement shows how long a watch will function when not worn. On a manual winding watch, it shows the time left until the watch needs winding. In Orient watches, rather than being a whole sub-dial, the indicator is just a small “alpha” style hand that points toward a single arcing index. This feature adds an interesting texture to the dial that watch enthusiasts learned to love.
