Seiko 5

Seiko 5 is a sub-brand of Seiko introduced in 1963, named for its five key attributes: automatic movement, day-date display, water resistance, recessed 4 o'clock crown, and durable construction. Originally created as the Seiko Sportsmatic 5, it became one of the world's most popular entry-level automatic watch lines. The brand was revived in 2022 as Seiko 5 Sports, offering modern interpretations of classic designs while maintaining affordability.
