During the early 1970s, legendary Swiss manufacture Zodiac established itself as a pioneer of experimental horology-most famously with their "Astrographic" mystery dials and optical color-shifting lacquers. This horizontal oval dress watch represents one of their rarest executions from that golden era.

The minimalist, markerless dial uses a complex multi-layered gradient coat that reacts dynamically to ambient light, shifting seamlessly from warm tobacco gold to deep emerald and midnight shadow. Preserved in museum-grade condition, it retains its factory-original soft suede strap and original signed Zodiac buckle.
