Unveiled at SIHH 2017, the L133.1 calibre continues the legacy of the 1994 Tourbillon 'Pour le Mérite' and the 2005 Tourbograph 'Pour le Mérite'. As the most complex in the series, it integrates a tourbillon and fusée-and-chain transmission with a rattrapante chronograph featuring two column wheels and a perpetual calendar. This movement is composed of 684 individual parts and 52 jewels.
