Automatic synchronization to the exact time.
Your Astron 5X watch adjusts automatically to the exact time, up to twice a day. If it can see the sky, it will connect with one or more GPS satellites and re-set the time, if needed, to a precision of one second every 100,000 years*. Even if the watch cannot see
the sky, it remembers when it was last successful in receiving a time signal and automatically attempts to receive a signal.
- Automatic time adjustments occur once daily with 8X Series, twice daily with 5X Series.
