Seiko Prospex Sea Ltd Edition SPB545J1.

Limited Edition:  4,000 pieces worldwide

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 refreshing blue dial paired with a subdued gray bezel creates a sophisticated and sporty aesthetic.
