SMA-Q Smartwatch Mini Review and Teardown

I had great hopes for SMA-Q smartwatch, as it features an always on color e-Paper display, a built-in heart rate monitor, and promised 30-day standby battery life, as well as being 30-meter water resistant. But last week, I found out that the latter did not mean waterproof, and instead the watch was rated IP65 that’s only good enough to wash hands and a little rain, but not showering let alone swimming. In the last week, I could play with the watch, and found some serious Bluetooth connectivity issues (with Iocean M6752 smartphone), and I was recommended to upgrade the firmware of SMA-Q watch, and after that my Bluetooth issue have somewhat improve, but everything pretty much went downhill, and the watch is now out of order, and shows no sign of life. So while I was expecting to write a full review, I’ll simply report with experience with the watch […]

Since I’ve listed the specs and torn down No.1 D3 smartwatch, I’ve spent several days wearing the smartwatch / watchphone, and trying most of its features, so it’s time for a review. I’ll go through all screens of the user interface, include a video review, before providing a conclusion to this review Charging the watch take between 15 to 30 minutes, and you can turn it on by pressing the only button on the side of the watch for a few seconds. The first menu you are likely to see if the one with the phone functions including the Dialer, messaging, phonebook and call logs.
