Audemars Piguet Yellow Gold Skeleton Automatic Watch Ref. 5442

It was during the winter of 1972 1973 that a few young watchmakers set about rediscovering openworking, undoubtedly aided and abetted by their elders. Georges Golays vision was ambitious, as the operation kicked off with a hundred examples of Calibre 2120. The first watch was delivered on November 31, 1973. A masterpiece of meticulous craftsmanship and fine detail, Model 5442 provided a complex stage-setting for its mechanism. Through the caseback, the openworked oscillating weight revealed the AP monogram, in a pattern that would inspire the weights of Calibres 2120, 2121 and 2120/2800 for decades. Five more timepieces were delivered in December and an average of 30 watches were produced annually until 1976. - AP Chronicles
