I may have gotten a dud, but the sensor watch pro board Unused had a _really_ bad crystal oscillator. Like, slow by over 30 seconds a day. There is the oscillator fine tune complication but the oscillator I had was way beyond the max adjustment range (32k ppm). Maybe it was just luck of the draw and I should give it another shot but having a clock that needed to be adjusted every few days was unusable.
