This watch is an automatic.  What this means is that it doesn't use a battery and self winds while you are wearing it and moving about.  If you don't wear it, you will need to gently cradle swing it with your hand for about 30 seconds to a minute to maintain the power.  It works best if you wear it every day.  If you don't wear it, it will eventually stop running usually a day or two. You will have to reset the time and date and cradle swing it again to wind it up again.

I have read the other reviews about time accuracy.  Automatics are not as accurate as a quartz watch.  An automatic can lose many seconds per month.  That is a characteristic of an automatic, but I don't mind it.  It is part of the appeal where you bond with the watch.  If you can't stand taking care of it, then a classy automatic is not for you.  The second hand movement does not have the typical tick style movement, but rather it gracefully sweeps across the watch face.  I can understand the appeal of early chronometers using this type of movement, and understand it's historic applications for time keeping.

In terms of looks, it is an eye catcher.  The bright orange face makes it easy to see in the dark or changing light conditions and the luminous markers on the hands and face of the watch holds a bright glow which gently fades after many hours.  I have woken up early in the morning noticing that the luminescence was still bright enough to read the time easily.  I have not taken the watch diving or snorkeling yet, so I cannot comment on water resistance, or on dives below 100 feet depth where the light spectrum starts to change.

This is my first automatic.  Most of my watches have been quartz powered military/government issue SAR watches.  This watch has the heavy duty look and construction of a military watch but classy enough to wear to work or a night on the town.
