Having made some of the world’s most iconic dive watches since their first foray into marine timepieces in 1965, Seiko has remained ahead of the curve with new shapes, innovations, and an endless march of limited editions. And with the announcement of the “Island Green” series, the tradition continues.

For its 140th anniversary, Seiko has chosen to commemorate several aspects simultaneously. First, is the unspoiled nature of Iriomote Island, a sparsely populated island in Okinawa Prefecture known for its immaculate diving locales and rich fauna. Imagining oneself in this verdant setting, it is easy to visualize Seiko’s second source of inspiration – the “morning twilight of early dawn” as a new day rises on the horizon. These scenes are captured in the deep green of the SSC807 and its cousins, the SPB207 and SLA047.

Limited to just 4,000 pieces, the richly-featured solar chronograph SSC807 sits on a steel bracelet and ships with a rubber strap for maximum options. With a new case shape based on the “Sumo” design, this watch is a joy to observe and even more pleasing to sport on your next dive excursion.
