Seiko Alba "Twin" Ana-Digi Chronograph, Dual Display (Ref. Y651-5090, 1980s)

Seiko Alba "Twin" ana-digi chronograph, reference Y651-5090, produced in Japan during the 1980s, caliber Y651 quartz movement shared across Seiko's Alba and Pulsar sub-brands. Stainless steel angular case with square geometric lugs, integrated brushed stainless steel jubilee-style bracelet flowing flush into the case architecture. Dual stacked display layout, top half a traditional analog two-hand quartz clock face signed "ALBA" and "QUARTZ," bottom half a rectangular digital LCD display. Digital toolkit includes stopwatch and lap chronograph, hourly chime, daily alarm, dual time zone tracking, and full calendar display, controlled via four corner pushers labeled Light, Dual/Date/Start-Stop, Unlock/Digi/Ana, and A.Stop/Reset/Select. Solid stainless steel case back.

Story of This Watch: The Alba Twin captures Japan's early-1980s appetite for maximalist multi-function watches, stacking a conventional analog dial directly above a full digital toolkit rather than choosing between the two. The dual time zone function alone made it genuinely useful for anyone moving between regions, and today it's the layered ana-digi design itself, unmistakably retro and mechanically ambitious for its era, that draws collectors back to this reference.
