The Seiko Prospex SRPK01 is a PADI Special Edition automatic dive watch built to ISO scuba standards. Its patterned, gradated blue dial mimics sunlight through water, and the blue ceramic bezel, LumiBrite hands and markers, and magnified day-date window carry the PADI theme. A 45mm stainless steel case, sapphire crystal, screwdown crown and caseback, and 200m water resistance make it a serious dive tool. The 4R36 movement offers about 41 hours of power reserve and manual winding. It suits divers and Seiko collectors who want a bold, purpose-built watch; at 45mm it wears large, and its size and weight are the main trade-offs against slimmer everyday divers.

Owners of the SRPK01 praise its ocean-patterned dial, strong lume and solid dive-watch build. Many note the 45mm case feels big and the 4R36 keeps time within a few seconds a day rather than precisely.
