Audemars Piguet “Grande Complication Automatique”

European Watch Clock and Jewellery Fair 1987 BF 215
In mechanical time, everything seemed to have been said and done... yet
now comes the world’s very first seifwinding, complex “Grande Complication” wristwatch. Born of close cooperation between a team of craftsmen at Audemars Piguet and the watchmaker Dominique Loiseau, it required no less than three years of research and development. The movement is composed of three superposed mechanisms : a perpetual calendar (date, day, month and moonphases) programmed until the year 2100; a selfwind-ing movement with minute repeater (striking hours, quarters and min-utes); a chronograph. With parts entirely cut and shaped by hand from pink or white 18K gold and a platinum rotor, the 27mm-diameter movement is only 7.30 mm thick
