Seiko Astron 145th Anniversary Limited Edition HAB004

145 Years of Seiko. Limited to 2,000 Pieces.In 1881, Kintaro Hattori founded a small clock shop in Tokyo. One hundred and forty-five years later, Seiko is one of the most respected watchmakers on earth — the company that introduced the world's first quartz watch in 1969, the world's first GPS Solar watch in 2012, and a relentless commitment to precision that has never wavered. The Seiko Astron HAB004 marks that milestone with a timepiece worthy of the occasion.Powered by the new GPS Solar Dual-Time Chronograph Caliber 5X63, this watch self-adjusts to atomic clock accuracy via satellite signal and runs for approximately 6 months on a full charge — or up to 2 years in power save mode. The titanium case with super-hard coating houses a light silver dial with blue accents inspired by Seiko Blue — a signature color established in the 1960s and refined over decades of Seiko heritage. The quick-change system allows effortless swapping between the titanium bracelet and the included exclusive blue-and-white silicone strap with a single push of a button. LIMITED EDITION is engraved on the case back. Only 2,000 pieces exist.One hundred and forty-five years of getting it right. This is the watch that proves it.Specifications Case Diameter: 43.4mm | Thickness: 12.4mm | Lug-to-Lug: 50.0mm Case Material: Titanium with super-hard coating Crystal: Sapphire with super-clear coating Bracelet: Titanium + exclusive blue-and-white silicone strap (quick-change) | Lug Width: 14mm Dial: Light silver with blue accents (Seiko Blue) Water Resistance: 10 bar (100m) Magnetic Resistance: 4,800 A/m Movement: GPS Solar Caliber 5X63 Precision: ±15 sec/month (without GPS signal) Power Reserve: Approx. 6 months (fully charged) | 2 years (power save) Functions: GPS time adjustment, world time (38 cities), dual-time, chronograph, perpetual calendar, day, power reserve indicator, DST, in-flight mode Reference: HAB004 Additional Details Brand: Seiko | Collection: Astron Limited Edition: 2,000 pieces worldwide LIMITED EDITION engraved on case back LumiBrite on hands and indexes Authorized DePaula Jewelers dealer
