Driven by rich legacy that has set the standard for dive watch specifications and a heritage of iconic design, Prospex continues to keep going forward with precision timekeeping, crafted for the modern world. Chosen by fans as the winning design among four models, this extraordinary Limited Edition is available only in a controlled production run of 4,500, with the serial number engraved on each caseback, and celebrates the anniversary of Seiko’s 1965 first diver’s watch. Framed by a coordinating uni-directional rotating elapsed timing bezel, the “daytime blue” patterned dial draws inspiration from the vibrant blue sea shining as it reflects the sunlight. The dial layout boasts excellent symmetry with LumiBrite coating on the hands and all 12 markers for enhanced visibility and includes a date calendar. Powered by motion, it is equipped with a 24-jewel automatic movement that beats at a frequency of 21,600 vibrations per hour and offers an upgraded power reserve of approximately 72 hours along with manual winding capability. Crafted of stainless steel with super-hard coating, this superbly collectible diver’s watch is enhanced with a curved sapphire crystal with anti-reflective coating on the inner surface, as well as a screwdown crown and caseback. Engineered with a 300 meter water resistance, the innovative creation preserves a streamlined case profile while incorporating a bracelet made up of links with a short pitch and a specially developed slide adjuster clasp with a double lock, allowing for easy size adjustment.
