Profile

Shohei Ohtani was born in Iwate Prefecture in 1994. Selected first overall in the 2012 Nippon Professional Baseball Draft, he joined the Hokkaido Nippon-Ham Fighters and gained attention for his two-way role as both pitcher and hitter. In 2018, he moved to Major League Baseball, where he has achieved tremendous success on the sport’s biggest stage.

Shohei Ohtani’s determination to grow and evolve resonates deeply with the Seiko Prospex philosophy to “Keep Going Forward.”
As both a pitcher and a hitter, he has performed at the highest level on both sides of the game, an achievement few thought possible. He has refused to be defined by convention, all while preserving the joy of playing the game. Step by step, Shohei Ohtani continues to build his achievements with confidence.

PROFESSIONAL SPECIFICATIONS

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.

ICONIC CASE DESIGNS

With heritage-inspired creations based on such landmarks as the first diver’s watch from 1965 and the 1968 300m high-beat diver, Seiko honors the iconic designs of the past while still staying true to its mantra of “Keep Going Forward”.

EQUIPPED WITH PRECISION

Seiko Prospex continues to set new standards with vigorous design and advanced automatic mechanical movements such as the high-torque, hand-assembled 8L calibers, engineered expressly for high-intensity timepieces, and the 8R mechanical chronographs, incorporating a vertical clutch and column wheel for smooth, stutter free operation. In addition, the 6L37 movement allows a slim profile while meeting the strict standards for diver’s watches and the upgraded 6R movements offer power reserves of 72 hours, three full days.
