Seiko Prospex Limited Edition SPB439J1

The mission of Seiko Prospex is to protect the world’s oceans now and for future generations, and to secure this legacy for divers everywhere. To this end, Seiko Prospex supports various marine conservation activities through its "Save the Ocean" initiative.
Today, Seiko Prospex introduces a new limited-edition diver’s watch GMT into the Save the Ocean series, which represents these conservation activities.

The new creation’s textured dial captures the power of the polar glaciers that shape the landscapes and seascapes of the Arctic and Antarctic. Accented by a light-blue GMT hand, the dial’s silvery-white hue and delicately striated surface create a unique depth that invites repeated looks.
