The watch measures atmospheric pressure from 260 hPa to 1 100 hPa (0.65 inHg to 32.45 inHg).
Approximately 5 minutes of direct bright sunlight are needed to raise the battery by one level; full charge may require longer exposure.
All functions stop, and the watch returns to its factory default settings; you must recharge before using it again.
