SRPF77 Manta Ray Diver

The Seiko Prospex SRPF77 "Manta Ray" Special Edition captures the essence of deep-ocean exploration through masterful design and engineering. Its gradient blue dial—inspired by light filtering through water—pairs with a wave-pattern texture for visual depth. The 24-jewel automatic movement delivers 41 hours of power reserve and operates at 21,600 vibrations per hour, supporting both manual and automatic winding. LumiBrite luminescence ensures visibility in low-light conditions, while the magnified day/date window enhances readability. A black ceramic uni-directional bezel, screwdown crown and caseback, and anti-reflective sapphire crystal provide the durability demanded by serious divers. ISO-certified for scuba diving with 200m water resistance, the 45mm stainless steel case sits on a deep blue silicone strap—a timepiece engineered for those who pursue adventure without compromise.
