An Audemars Piguet grand classic, the calibre 2003 was designed in 1946. To celebrate its fiftieth anniversary this year and its undoubted influence on the evolution of a large number of the braiid’s models, the Manufactory has produced a men’s model in a limited series of 300: 150 in yellow gold, loo in pink gold and 50 in white gold. Both the interior and exterior are modernised versions of the 1946 model.
