WHAT IS AN AUTOMATIC WATCH?
An automatic watch, is a type of mechanical watch. These
watches do not use an internal battery and instead uses the
natural motion of the wearer to provide energy to run the watch
(making manual winding unnecessary).
Once fully “charged”, your Dark Water 300 has a typical power
reserve of around 40 hours. If you stop wearing your watch, you
may notice that it has stopped running after a certain length of
time. Don’t be alarmed, you simply need to energize your watch.
