I see this issue was also posted 2 years ago. I've recently bought the watch and it resets; metric to imperial, alerts, 24 hour clock and some other settings at seemingly random intervals. v3.60 is the software version and no updates are available. I've checked the mobile app and the only one of these I see it the 'metric' one and it's set correctly to 'metric' - any ideas as it's a tad annoying?
