Prospex, short for "professional specifications", is Seiko's line of sports and tool watches: divers, field watches and chronographs. It draws on Seiko's dive watches since 1965, and many models are certified to the ISO 6425 diver's standard.
Prospex covers mechanical, Solar and Kinetic movements and many re-editions of historic divers, so the reference matters: it tells you the movement, case size and dial. Check the bezel action and the lume in the photos.
We stock 432 Seiko Prospex watches, from $245 to $5,985.
