From the introduction of its first sports watch in 1959, Seiko has been the choice of adventurers and explorers, while spearheading innovations in both technology and design. Prospex, short for “Professional Specifications” continues this legacy with both diver’s models for the sea and sport’s watches for the air and land.


With re-creations and re-interpretations of such landmarks as the first Diver’s watch in 1965, it’s first high-beat diver in 1968, and the first titanium professional saturation diver’s model in 1975, Seiko honors the iconic designs of the past while still staying true to it’s mantra of “Keep Going Forward”.


Seiko Prospex continues to set new standards with vigorous design and advanced automatic mechanical movements such as the high-torque 8L35 caliber, hand-assembled at the Shizukuishi Watch Studio in Japan, the ultra-slim yet powerful 6L35 caliber, and the 6R35 with its remarkable 70-hour power reserve.
