The clock itself is outstanding, looks top and runs from OS problems. On the Meaning of "SmartWatch" suggests this product Android wearables, Pebble and Apple Watch by far. Unfortunately, I can still be only two stars. The reason for this is that I have ordered two copies and does not work for both the GPS. An approximate location is found quickly over wireless / data connection, but the exact location from the GPS is not found. Because I need the clock for navigation and geocaching, for me a no go. This is still the my SD card is not recognized in one copy and copy two the display at one corner of minimal distance.
I sincerely hope that the follow-up model works better, I want this clock.
The battery life with deactivated data connection is very good per day about 20% under normal use, a display on Time of 4.5 hours in there, perfect!
By the way, all Android apps I've tested (c: geo, HERE Maps, Spotify, Screen off & lock, Nova Launcher) run smoothly. The latter App is the way my secret, because the Nova Launcher makes the clock perfectly adaptable.
