Might an app be developed to record a reference time setting and pull the Bangle close to that when it drifts by a certain amount? I suppose that's asking a wayward crystal to monitor itself and is impossible, unless there's an external way to keep track of the seconds, such as connecting to wifi or a cellular phone tower. A GPS setting would correct the time but is a battery-intensive and cumbersome corrective.
Suggestions welcomed.
