The Seiko 6159-7000 isn’t just another dive watch—it’s a piece of horological history. Released in the late '60s, this was Seiko’s first hi-beat professional diver, and it laid the groundwork for the brand’s serious tool watch game. With a 44mm case, screw-down crown, and legendary 6159 movement, it was built for saturation diving but still wears well today. This example features a black dial with vintage lume and comes on a non-original rubber strap that’s ready for daily wear. If you're into iconic sport watches that helped shape the dive category, this Seiko deserves a spot in your rotation.
