The Seiko Prospex SPB421 is a limited-edition stainless steel dive watch with a deep blue dial inspired by Alaska's glacial moulins. It is rated to 200 meters, runs on an automatic movement with a 72-hour power reserve, and comes on a steel bracelet. It suits divers and collectors who want a distinctive dial with serious water resistance. Against Seiko's core Prospex divers it adds a limited-run design and a longer power reserve, but it carries more of a premium than the standard models.
