Jaeger-LeCoultre – Master Grande Tradition Gyrotourbillon Westminster Perpétuel

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.

Price: $893,000 in 18K white gold
