Thanks to six years of research and development, the Master Grande Tradition Gyrotourbillon Westminster Perpétuel watch is one of the most complicated pieces ever produced by Jaeger-LeCoultre. It is the brand's fifth Gyrotourbillon (an escapement with multiple-axis tourbillons rotating at different speeds). This model was particularly difficult for the brand to create because it is 15 percent smaller than any other version, a feat of miniaturization that took three years. The new movement, Caliber 184, consists of a staggering 1,050 pieces and offers constant force (constant energy from full power to end of power), a perpetual calendar that can be set forward or backward, and a minute repeater with a retractable pusher that sounds the time using Westminster chimes with four gongs.
