[product_description]Astron GPS Solar Titanium Limited Edition. Celebrating a decade of GPS Solar technology, this landmark Limited Edition is designed for a new generation of leaders, embodying the pursuit of excellence in both innovation and style. With the strong, sleek lines of the Seiko Astron, the world's first commercially available quartz watch, this remarkable timepiece, available only in a controlled-production run of 1,500, combines solid tailoring with the highest degree of accuracy possible in a wristwatch. GPS controlled for high-speed time and time zone adjustment to 39 time zones, and including a daylight saving time function, perpetual day and date calendar correct to the year 2100, and am/pm indicators, this exceptional watch features a unique time transfer function that 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. With distinctive horizontal patterning to reinforce the solidity of the design, the gray dial, complete with three-dimensional applied indices and LumiBrite hands and markers for superior visibility, is framed by a black sapphire crystal bezel providing subtle dimensionality, shine and enhanced scratch-resistance. Crafted of light and durable titanium, with a 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): 42.7ö|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: Grayö|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 Titanium Limited Editionö|Celebrating the 10th Anniversary of the GPS Solar Astronö|Limited edition of 1,500ö|GPS Solar Dual Timeö|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|Gray dial with distinctive horizontal patternö|Date calendarö|LumiBrite hands and markersö|Three-dimensional applied indicesö|Screwdown casebackö[/unique_description_2]
