I have it 4 stars because you can't always feel when to stop winding and so it will stop when it runs out. You do not always know when that'll be. I now wind it every 12 hours. The watch itself is cool as hell. The band is easily adjusted. There are multiple clasps to keep it attached. I love being able to see all the mechanics inside. I love that you can wash your hands without taking it off!!

Horrible ! Will not keep correct time......it's ticking but not a correct speed. I was late to 2 different meetings because it was running slow. Not a good buy.
