Seiko Prospex Save the Ocean

The watch uses a quartz movement, so it is designed for dependable timekeeping with low routine maintenance. Its dive-oriented design also includes luminous elements for easier reading in low light.

It is built for underwater activities, with a robust titanium case and bracelet and a lumed bezel. Check the exact reference for its certified water-resistance rating before using it for professional diving.

The Save the Ocean editions connect the Prospex sport-watch line with ocean-conservation initiatives. They commonly use marine-themed designs and partnerships while retaining practical features such as luminous dive markings.

The item described here is quartz, which means it runs from a battery rather than winding itself through wrist movement. That distinguishes it from automatic Prospex divers such as many Seiko Turtle models.
