Seiko Duo-Display (Ana-Digi) in Steel – Cal. Seiko H601

A striking Seiko Duo-Display (Ana-Digi) from the 1990s, combining traditional analog time indication with an LCD digital display at 6 o’clock. The ivory dial with geometric pattern, the sharply lined case, and the integrated steel bracelet fully express the technological, experimental Seiko design of those years.
