New: Alina Y118 35

The original Y118 had slow, sometimes erratic GPS. The "35 New" uses a dual-band L1+L5 GNSS chip supporting GPS, GLONASS, Galileo, and BeiDou. In field tests, the watch locked onto satellites within 12 seconds (cold start) and tracked routes with an error margin of under 2 meters, comparable to a Garmin Forerunner 55.
