Runner 3 will not hold current time or time an activity
edited January 24
Have tried factory reset, letting battery run down etc. Watch is 2 years old. Running 1.7.64
If a factory reset did not do anything there is nothing else to be done. You are out of warranty and TT Sports went out of business over 2.5 years ago. Time to toss it and get a new watch. There are brands out there with more features for less price these days.
