An emblem of Japanese precision from the golden age of mechanical watchmaking.
The Citizen Crystal Seven 33 Jewels is a mid-century automatic that epitomizes refinement and reliability. Introduced in the late 1960s, the “Crystal Seven” line marked Citizen’s innovation in using hardened mineral glass — a first in their lineup. This reference, powered by a 33-jewel automatic movement (Cal. 5207), delivers smooth timekeeping with day-date functionality at 3 o’clock.
The silver sunburst dial, framed by faceted indices and dauphine hands, captures the minimalist design ethos of the era. The case’s gentle curves, Citizen-signed crown, and original stainless-steel bracelet with signed clasp underscore the watch’s authenticity and period-correct appeal.
A timeless companion that bridges everyday utility with vintage Japanese engineering finesse.
