Zeblaze Stratos: GPS smartwatch with a barometer, compass, GPS and 5 ATM water resistance starts globally for US$79.99
The Zeblaze Stratos is another comparatively cheap smartwatch from the company that released the Vibe 3S HD and Thor 6, among others. According to Zeblaze, the Stratos has a 1.32-inch display surrounded by a zinc alloy bezel and a carbon fibre-reinforced polymer case. The smartwatch also has a replaceable 22 mm strap, which is always good to see.
The Stratos may not have an LTE modem, but it supports Beidou, Galileo, GPS and GLONASS location services. These tie in with the 120+ exercise modes that the smartwatch has, as do its heart rate monitor and SpO2 sensor. Zeblaze claims that the Stratos is 5 ATM water-resistant too, making it suitable for diving and swimming. Moreover, the Stratos has a barometer and an e-compass, should your workouts take advantage of those.
The smartwatch communicates with Android 6.0 or iOS 9.0 and newer devices via Bluetooth 5.0 (BLE 5.0). Apparently, the Stratos should last up to 25 days on its 580 mAh battery, although this may be a generous estimate on Zeblaze's behalf. Currently, the Zeblaze Stratos is available on AliExpress from US$79.99.
