Watch Seiko SSH003J1 Analogue steel case and bracelet Astron 5X collection.Temple with a 42.9 mm diameter high density titanium case with scratch-resistant coating, gray dial with date display, ceramic bezel, hour markers and spheres with Lumibrite. Titanium, push-button closure Waterproof up to 10 Bar Model Astron 5X GPS Solar Dual Time Zone Like all Astron GPS solar-powered gauges, the 8X42 automatically switches to local time, all over the world, with a simple pressure, producing its energy solely thanks to sunlight.With the addition of a Grande Data 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 in the world.) For the first time, several dials in the collection show Roman numerals and other components with mirror finishes.The Astron watch then sports a style more urban. If a new time zone should be created, manual adjustment may be required. When you connect to the GPS network, just press a button to set the new Astron to your time zone . Moreover, 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 GPS satellites at 20,000 km away. As soon as the dial is exposed to a sunray, 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 time or time setting, and automatically starts setting the time at the same time. An exclusive Seiko ring antenna, located under the inner bezel of the dial, allows automatic reception because it receives signals easily, regardless of the position of the person wearing the watch. Consumed with original box and official warranty. " bf22
