The new product retains the 1.43-inch AMOLED screen with a resolution of 466×466, but gets a more massive metal case with four large buttons and Gorilla Glass protection with a 9H hardness rating. About 270 dials are available to users. The main advantage of the device — outstanding durability. In addition to the standard 5 ATM water protection, the watch is IP69K certified for industrial equipment. This means resistance to high-temperature and high-pressure water jets, dirt, drops and sand. The main advantage of the watch is that it is resistant to high-temperature and high-pressure water jets, dirt, drops and sand. GS3 Ultra supports over 160 sport modes with auto-detection of popular workouts and monitors heart rate, blood oxygen levels, stress, and multi-stage sleep, including short daytime naps. Substantially updated navigation capabilities — there’s now dual-band GPS (L1 + L5) and support for all major satellite systems: BeiDou, GLONASS, Galileo and NavIC. You can take calls via Bluetooth, and ENC technology reduces ambient noise. One of the most impressive parameters was the battery life: up to 18 days of normal use and up to 45 days standby — a significant margin compared to many modern smartwatches.
