Seiko SRPF77 Prospex Special Edition Blue Silicone Automatic Day Date Diver

Seiko SRPF77 Prospex “Manta Ray” Dive Watch

The Seiko Prospex Special Edition SRPF77, nicknamed the “Dark Manta” or King Turtle “Save the Ocean,” blends bold underwater performance with refined design. A rich gradient blue manta-ray dial—embellished with wave‑pattern stamping captures the shifting light of the deep sea. Powering the piece is Seiko’s in-house Caliber 4R36 automatic movement, offering approximately 41 hours of reserve and manual winding capability. Housed in a 45 mm stainless‑steel case with a black ceramic uni‑directional bezel, its scratch‑resistant sapphire crystal with anti‑reflective coating ensures clarity under pressure. Designed for serious diving, it delivers ISO‑certified 200 m water resistance and features luminous LumiBrite hands, markers, and bezel for exceptional low‑light visibility. Completing the rugged, adventure-ready aesthetic is a deep blue silicone strap, secure screw‑down crown and caseback, and magnified day/date display at 3 o’clock.
