The watch is great and the battery life is amazing. I would have given it 5 stars except for the mineral crystal!! It should ha e been a sapphire crystal like all regular Citizen watches. The mineral crystal scratches very easily and cheapens an otherwise amazing smart watch.
This is a great watch! I found the setup easy to do and the information it tracks is exactly what I wanted. The only issue I found was that they haven't opened their api so the sleep tracking app I use, Sleep as Android, can interface with the watch. Other than that, it's great. Battery life is excellent as well.
