Great watch, Only issue is you might have to watch the video a few times to understand everything wonderful thing it does.
Cool watch! I was looking for a watch that does not need batteries. These watches are very nice. They have very thick bands as well, not those cheap bands that break after a few months. I would not buy this watch because of the quality of its compass or altimeter as they more for reference than accuracy, but if you're ok with that these are fabulous looking and working watches.
