Dear watch aficionado.
These Audemars Piguet 5402ST A-Series are much sought after timepieces. To find them in great condition in full spec combination as the present example is highly rare. It all started back in 1972 when Gerald Genta designed the Royal Oak for Audemars and it is the watch that saved Audemars from closing their doors.
The present watch is in great condition, it retains a super strong case, firm original bracelet, original and matching clasp, original crown, 2 AP links. The dial is in splendid condition, made with the "tapisserie" method and then finished in black galvanic bath and then a thin translucent lacquer to protect the dial from oxidation.
I warmly invite you as well to take a look at the article on my blog about the design of the dial by Gérald Genta of the 3700/1 and AP 5402ST A-Series.
