Caliber 5X53 adjusts at the touch of a button to your time zone* by connecting to the GPS satellite network and, as it takes all the energy it needs from light alone, it never needs a battery change and yet delivers the astonishing precision of an atomic clock, one second every 100,000 years. *If there are changes in the region / time zone / DST, manual selection may be required.
When the watch dial perceives sunlight, the watch connects to the GPS satellite network and adjusts automatically to the correct time. If the watch is hidden from light, it remembers the time of its last successful manual connection and attempts to receive the GPS signal again at that same time.
For example, only 3 seconds are needed to advance 14 hours from Tokyo to New York time, thanks to the system that moves hour, minute, and seconds hand independently.
In the caliber 5X53, if time zone adjustment is successful, the watch will display local DST. (This will not apply when time zone is selected manually)
Caliber 5X even gives the wearer the ability to change the main time display instantly from home to local time and vice versa.
