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.
