I have mixed feelings when it comes to this watch. Overall it does a decent job of keeping track of your heart rate, blood oxygen level and the steps you have walked throughout the day and the watch looks rather nice. However I feel that the user interface is rather clunky and at times it appears to lag sometimes taking 10 seconds before it does what you ask it to. Also I find that it misses a few of the exercise options that I participate in. This is somewhat remedied by the fact that you can pair the watch to work with Google Fitness which does an excellent job of tracking your exercise and it has many of the options that I participate in.
I have had an iWatch for a long time. So to try the CZ smart watch was exciting. It came up short though. The software seemed to be a little laggy. I was not a fan of the not being able to speak on it. One day the watch just stopped communicating with my phone. It is nice but I did not have the greatest experience with it.
The watch is beautiful but, being a hybrid, has only limited Smart Functions and too small digital display. The mechanical hands get in the way of the display. It would have been better if they made it 100% digital. The screen is also inconsistently responsive. I had a hard time connecting to the app. Often it would not find the watch. I would wear this because it looks cool but the smart functions are weak.
I bought this watch mostly to track my running distance and I like it much more than I anticipated. I like that it has actual physical hands and that the display is very minimalist without any clutter. The battery life is awesome (like 2 weeks on one charge). There are two things I wish would be different but there is no way to give 4.5 stars :-) 1) I wish the hands were illuminated. When I run in the morning I cannot really see the time. The display light is hard to activate (it should be on double tap but works for me only sometimes) and does not really help much (it's very uneven and the hands are still hard to find). 2) The glass is mineral. I wish it was sapphire. I have a few other watches and they all have sapphire crystal so it should not be a big deal.
