To mark 110 years of watchmaking excellence, Seiko is highlighting its continuous dedication to evolving technology, as well as diversity, equality and the sustainable manufacturing necessary to meet environmental challenges. Based on an iconic design, this landmark automatic diver's watch, available only in a controlled-production run of 5,000, with the serial number engraved on each caseback, also extends the Prospex tradition of celebrating its rich legacy of innovation in high-intensity timekeeping by recreating and reinterpreting signature achievements. Expressing the power of nature, the three-dimensional pressed pattern silver dial suggests the majesty of Ice Age glaciers transformed through millions of years of cooling. Framed by a gray uni-directional rotating elapsed timing bezel, the dial also features LumiBrite hands and markers, as well as a date calendar. Following ISO standards for scuba diving to depths of up to 200 meters, this exceptional timepiece includes a 24-jewel automatic movement with a frequency of 21,600 vibrations per hour, a power reserve of approximately 70 hours, and manual winding capability.
