Ceramic bezel, indexes and spheres with Lumibrite. Bracelet titanium, push-button closure Waterproof up to 10 Bar. Astron 5X GPS Solar Dual Time Zone Like all solar Astron GPS calibers, the 8X42 automatically switches to local time, all over the world, with a simple push, producing its energy solely thanks to the sunlight.With the addition of a large date window, a second time zone at six o'clock and new finer hands, these new models show a refinement suitable for all occasions (evenings or trips around to the world.) For the first time, several dials in the collection show Roman numerals and other components with mirror finishes, and the Astron watch shows off a style. more urban. If a new time zone is created, manual adjustment may be required. When connecting to the GPS network, just press a button to set the new Astron to your time zone. Furthermore, because it uses only solar energy, it does not need a new battery. When it receives GPS signals, the minute hand starts moving, indicates the number of satellites and then displays the current time. It is moving to hear the identification of the GPS satellites at a distance of 20,000 km. As soon as the dial is exposed to a ray of sunshine, the watch automatically receives GPS signals. When the watch is hidden under a sleeve and the dial does not receive enough light, it records the time of the last successful manual setting of the time zone or time, and automatically starts to set the time at the same time. An exclusive Seiko ring antenna, placed under the inner bezel of the dial, allows automatic reception because it receives signals easily, regardless of the position of the wearer of the watch. Permitted with original box and official guarantee. bf22
