This Save the Ocean Limited Edition is inspired by the beautiful ocean colors of Okinawa, one of the world’s premier diving destinations.

A dial that captures the beauty of Okinawa’s ocean waters
The ocean surrounding Okinawa is renowned for its breathtaking beauty, with crystal-clear water revealing white sandy seabeds. This watch features a sunray-patterned blue dial that reflects light beautifully, evoking the serene image of sunlight shimmering on the ocean’s surface.

A refined color combination

A new clasp designed for comfort and operability
The new clasp can be adjusted in six steps, each Seiko power design project measuring about 2.5mm, for a total range of approximately 15mm. It allows for a comfortable fit at all times, accommodating changes in wrist size during diving and daily life.
