Jaeger-LeCoultre unveiled two complex models, including the Duometre Grande Complication A Grande Sonnerie. This piece contains 1,300 parts and 15 complications, such as a flying tourbillon and Westminster chimes. The brand also introduced the limited edition Master Hybris Artistica Calibre 945, which utilizes grisaille enamel to create a celestial star chart on the dial.
