Inspired by the lush green of Yakushima’s primeval cedar forests, the limited edition is fashioned with a dark green dial. Yakushima is Japan’s first Natural World Heritage site, and like our Prospex watches, Yakushima’s diving sites are renowned for their exceptional visibility. The green of Yakushima breathes new life into this classic diver’s design.
Yakushima is located in the south of Japan and registered as Japan’s first Natural World Heritage site in 1993. As well as being a World Natural Heritage Site because of its forests, Yakushima is a much loved destination for the diving community, thanks to its crystal clear waters, coral reefs and abundant marine life.
The deep green dial
Its signature feature is the green color. This rich shade of green reflects the lush tones of the ancient cedar trees on the island of Yakushima at the southern end of the Japanese archipelago.
A bezel designed for a purpose
The professional level of the specifications becomes clear when you study the precise and secure operation of the uni-directional bezel. Its 120 ratchet design delivers more precise use and greater safety and the deep grooves make its operation easier and more secure, even at depth.
Highly durable zirconia ceramic bezel
The Zirconia ceramic will last a lifetime and longer, protecting the watch from rust and scratches so that the beauty of its deep green color endures for years to come, just as the verdant beauty of the forests of Yakushima has always remained pristine.
A special long-lasting LumiBrite coating on the hands ensures legibility at greater depths for longer than ever before. The 5, 10, 15, and 20 minute markers on the uni-directional rotating bezel are also coated in this new LumiBrite, adding extra security for divers.
Movement: Caliber 8L35
This limited edition is equipped with the high-grade caliber 8L35, which is hand assembled and adjusted by Seiko’s master watchmakers at the Shizukuishi Watch Studio in Morioka. Assembled from 192 parts, it beats at 28,000 vibrations per hour and has a power reserve of 50 hours.
A limited edition of 1,968
Made in celebration of the fiftieth anniversary of the first Seiko 300 m Hi-Beat Diver’s watch, just 1,968 of these watches will be made. Each watch has the word “Limited Edition” and its unique serial number engraved on the back. It is offered in its own special presentation case.
An extra strap
This Limited Edition is presented on a stainless steel bracelet, with easy to adjust size settings. A second attachment is also offered. This is a strap, made from high-strength silicone which is extremely resistant to sea water and perspiration sweat as well as being perfect for diving use with its accordion-style structure which allows it to expand and contract as the underwater pressure changes.
