Prospex Automatic Diver’s Watch. Designed for those who treat life as the ultimate adventure, the Seiko Prospex collection meets every challenge with technological excellence and style, continuing the rich legacy of innovation in high-intensity timekeeping. Framed by a coordinating polygonal uni-directional rotating elapsed timing bezel, suited for formal occasions while keeping an active and sporty impression, the warm blue pressed pattern dial, inspired by a calm coastline, offers a date calendar between 4 and 5 o’clock allowing for LumiBrite coating on the hands and all 12 markers, improving symmetry and legibility. With an upgraded power reserve of approximately 72 hours, 3 full days, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour and features manual winding capability. Crafted of stainless steel with super-hard coating, this superbly functional diver’s watch includes a sapphire crystal with anti-reflective coating on the inner surface, as well as a screwdown crown and caseback. The bracelet is designed with mirror polish center links to match the sophisticated case design, which follows ISO standards for scuba diving to depths of 300 meters while maintaining a slim profile.
