Fighting with BangleJS2 smartwatch. It can compensate for clock drift... But according to my measurements, error is on order of 600ppm... which is 10x what compensation app seems to be expecting. OTOH 600ppm is 50seconds a day, and that's in line with drift I was seeing.

@pavel isn't that why there should be an RTC crystal in there?

@martijnbraam My understanding is that 600ppm is not unusual for cheap, uncalibrated RTC.
