This bestselling watch pioneered the era of self-winding watches throughout the world and reinforced Seiko’s reputation for outstanding quality and reliability.
The Sportsmatic 5 came with a simple self-winding mechanism (magic lever), excellent waterproof structure, easy-to-read 'day and date'-integrated window display, shockproof 'diashock' mechanism, and several other novel features. It soon became the world’s norm for a practical watch.
