🛰️ Seiko Astron SSH011J1: The most advanced GPS Solar of all time
"Caliber 5X53 drives the most advanced Astron GPS Solar collection of all time." A completely new caliber with "high-speed time zone adjustment" and "time transfer function". Thanks to the use of three independent motors for the hour, minute and second hands, caliber 5X53 requires, at most, three seconds to change from one time zone to another. Simply by pressing the two and four o'clock buttons simultaneously, the 5X caliber changes the home time on the main dial to the destination time and, at the same time, changes the destination time on the secondary dial to the home time. Astron 5X53 automatically adjusts to the exact time, up to twice a day. If the watch can see the sky, it will connect with one or more GPS satellites and reset the time with an accuracy of one second every 100,000 years, if necessary. Titanium case of 43.5 mm with ceramic bezel, super-clear sapphire crystal and titanium and ceramic bracelet. Perpetual calendar, screw-lock back and water resistance of 10 ATM (100 meters).
