Jaeger-LeCoultre has launched a new limited-edition platinum version of its Duometre Heliotourbillon Perpetual Calendar watch for 2026. The reference Q6206150 model features a 44mm platinum case and matching bracelet with a gray dial. It is limited to just 20 pieces priced at $580,000.
The watch builds on the original gold model introduced in 2024. It houses the in-house Calibre 388 movement, which uses two separate mainspring barrels each providing a 46-hour power reserve. One barrel drives the Heliotourbillon regulator while the other powers the perpetual calendar.
The 14.7mm thick case includes a sapphire window on the side for viewing the tourbillon. The movement operates at 3Hz and allows safe forward and backward setting of the calendar via the crown.
Jaeger-LeCoultre designed the Heliotourbillon to improve accuracy in wristwatches by combining rotation with a swaying motion that covers most positions. The new five-link platinum bracelet complements the sober gray tones throughout the dial and case.
The limited edition emphasizes both technical complexity and classic dress watch proportions while remaining wearable despite its substantial weight.
