This is a custom-built Seiko watch, often referred to as a "mod." These modifications typically involve replacing various components like the dial, hands, and bezel insert to create a unique aesthetic, often resembling a Rolex Submariner. The custom dial features the word "Relax" in place of the typical Rolex branding. It uses an NH35A automatic movement.
