[product_description]Astron GPS Solar 5-X Titanium Dual Time Collection. With the strong, sleek lines of the Seiko Astron, the world’s first commercially available quartz watch, today’s Astron is designed for a new generation of leaders, embodying the pursuit of excellence in both innovation and style. Combining solid tailoring with the highest degree of accuracy possible in a wristwatch, this exceptional timepiece is GPS controlled for high-speed time and time zone adjustment to 39 time zones, and includes a daylight saving time function, perpetual day and date calendar correct to the year 2100, and am/pm indicators. The unique time transfer function allows wearers to switch between the main dial time and the dual time subdial at the push of a button. To ensure smooth operation, the watch is equipped with a signal reception result indicator and power save function. The solar cell is powered by light energy, with no battery change required. Featuring three-dimensional applied indices and LumiBrite hands and markers for superior visibility, the blue dial, with sunray pressed pattern and three contrasting black subdials, is framed by a blue ceramic world time bezel providing subtle dimensionality, shine and enhanced scratch-resistance. Crafted of light and durable titanium, with a black super-hard coating for added endurance and H-shaped links for smooth wearing comfort, this superb timepiece also offers a sapphire crystal with super-clear coating, secure screwdown caseback and tri-fold push button release clasp. 10 bar, 100M Water Resistant[/product_description][unique_description_1]Technology: Solar GPSö|Caliber 5X53ö|Powered by light energy – no battery change requiredö|Case Diameter (mm): 43.1ö|Case Thickness (mm): 12.2ö|Case Length (mm): 48ö|Case Material: Titanium case with super-hard coatingö|Crystal: Sapphire crystal with super-clear coatingö|Dial Color: Blueö|Strap: Titanium bracelet with super-hard coatingö|Water Resistance: 10 bar 100 meters (330 feet)ö[/unique_description_1][unique_description_2]Astron GPS Solar 5-X Titanium Dual Time Collectionö|GPS Solar Dual Timeö|Powered by light energy – no battery change requiredö|Perpetual day and date calendar correct to the year 2100ö|High speed GPS time and time zone adjustmentö|Dual time indicator (39 time zones)ö|Time transfer functionö|AM/PM indicatorö|Signal reception result indicatorö|Daylight saving time functionö|Power save functionö|Blue ceramic world time bezel provides dimensionality, shine and enhanced scratch resistanceö|Blue dial with sunray pressed patternö|Three black subdialsö|Date calendarö|LumiBrite hands and markersö|Three-dimensional applied indicesö[/unique_description_2]
