Powering your NH35A Automatic Movement
Automatic watches are powered by the motion of the rotor swinging around inside the case
Power by motion of swinging rotor
Simply give it a few shakes, back and forth, and you should see the watch’s hands start to move. If you’re someone who isn’t very active, like those who work at a desk job, it’s possible your watch will stop again sometime during the day, as it’s mainly powered by motion. You can keep it running by giving it a shake every so often, or simply by moving around more.
Manually winding the crown to power your watch
Unscrew the Crown
Unscrew the crown in a Counter Clockwise direction until you feel the crown spring loose. To screw the crown back in, push the crown in and rotate in a Clockwise direction until it stops. Do not over tighten. Hand tight is good enough to seal the crown down.
Wind the main spring
Once you have unscrewed the crown, turn the crown in a clockwise direction 30-40 times to wind the mainspring and power the watch fully. This will usually give it a power reserve charge of about 40 hours, give or take.
