    Only a very special timepiece would be worthy of such a moment. To celebrate the 100th anniversary of Seiko’s very first wristwatch, a unique, limited edition Astron watch has been created carrying, on the case back, the name of Seiko’s founder, Kintaro Hattori, and his often-repeated vision that Seiko should always be “one step ahead of the rest”. Furthermore, it carries the very first symbol mark for Seiko, registered in 1900, as an engraved and embossed center piece on the case back, and Kintaro’s birthplace, Tokyo, is remembered with gold lettering on the time zone bezel. The case is made of high-intensity black titanium, its crown is tipped with onyx, the crystal is coated in Seiko’s proprietary anti-reflective finish and it is offered with a crocodile strap and an additional titanium bracelet. This extraordinary watch is offered in a
limited edition of 5,000.
