esigned for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch excellence with re-creations and re-interpretations of landmark achievements. Inspired by the Aurora Borealis or Northern Lights, with a subtly gradated dial pattern evoking the changing colors of the night sky, this exceptional limited edition is available only in a controlled-production run of 500, with the serial number engraved on each caseback. Re-interpreting Seiko's renowned 1970 diver's watch, a favorite of such daring adventurers as Naomi Uemura, the first person to reach the North Pole solo, this extraordinary timepiece offers updated technology and a durable stainless steel case and bracelet with super hard coating.
