The Seiko Prospex SRPG57 is a Save the Ocean model. Seiko donates a portion of the sales to the Fabian Cousteau center. This particular watch has a crisp textured blue and white (ice-tone) dial with a few winsome penguin feet. The movement is a reliable 24-jewel Seiko caliber 4R36 automatic that can be hand wound and hacked. The powerful Seiko LumiBrite luminescent material is still used and it retains the same brilliant glowing properties that made the Monster such a huge worldwide phenomenon. A nice touch on this new model is that the case back indicates that it is a special edition.
Lug width is 20mm. Case size is 42mm in diameter x 13mm thick and 48mm tip to tip. It has a slightly domed Hardlex mineral crystal and a concave (120-click) dive bezel to help protect the crystal. The supple Monster bracelet uses a pin and collar system to size the solid link bracelet. Fine adjustments can be made on the push-button deployment clasp. Water-resistant to 200 meters. Day and date window. Screw-down crown and case back. Weight is 187 grams.
