Seiko Prospex SRPF77

Prospex Special Edition “Manta Ray” Diver. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and winning design. Inspired by Seiko’s most iconic diving styles, this distinctive Special Edition evokes the world view of a manta ray with the rich, dark gradated blue of the dial suggesting the variations in sunlight as it penetrates deep into the ocean, heightened by a stamped pattern suggesting waves. For reliable timing in rough waters, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 41 hours, and can be wound manually or automatically. Featuring a magnified day/date calendar and LumiBrite hands and markers, the dial is framed by a black ceramic uni-directional rotating elapsed timing bezel. In stainless steel, with secure screwdown crown and caseback, anti-reflective sapphire crystal and deep blue silicone strap, this high-intensity timepiece follows ISO standards for scuba diving. 200m Water Resistant
