Audemars Piguet “Montre Philosophique”

European Watch Clock and Jewellery Fair 1982 BF 2001
A new Audemars Piguet design : the “philosophical watch”. Its one and only hand shows both hours and minutes on a special 60-division dial. A turning-bezel featuring a marker (gemstone or gold stud) enables to read the time in another time-zone very easily. Case in 18K gold, extra-thin handwound movement.
