► ARCHIVE FILE: ALBA — BRAND HISTORY
Seiko launched Alba in 1979 as an affordable, youth-focused brand for Japan and other Asian markets. Its playful 1980s ana-digi watches, 1990s Spoon models, and other short-lived experiments made it a home for ideas too unconventional for the Seiko name—and now make original Alba watches especially appealing to JDM collectors.
