Very accurate watch (it only took a minute in a month) with a beautiful aesthetic military watch. The power reserve is a bit short (15 to 16 hours) but considering the price it is a bargain. Night vision requires that the watch is illuminated (sun or lamp) for a while. Excellent to see the time in a tunnel when the door with short sleeves. The appearance is now more attractive. By cons, if you wake up in the middle of the night you will not see much in the dark.
