5 Sports
Seiko’s long-running entry-mechanical line — the original Seiko 5 launched in 1963 as the brand’s "5 essentials" (automatic, day-and-date, water-resistant, recessed crown, durable case + bracelet). The modern 5 Sports relaunch (2019) carries the 4R36 caliber and a SKX-style case at the brand’s most-accessible mechanical price band.
