European Watch Clock and Jewellery Fair 1991 BF 401
This complex wristwatch design is cased in prestigious platinum. Its mechanical or quartz electronic movement drives a “perpetual” type calendar that provides the date, day, week, month, leap years and astronomical moon phases along with a 2k-hour-base time readout. Its date indicator is notable for its semi-circular construction : at the end of every month, its pointer springs back to the “1” position. Water-resistant case, screwlocked crown, setting by pushpieces. This “perpetual calendar watch” is exclusive to CHOPARD GENEVE.
