Description

The Jaeger-LeCoultre Duomètre Heliotourbillon Perpetual Q6202420 debuted in 2024 as part of a limited edition of 20 pieces. It introduces a newly developed triple-axis tourbillon housed within a pink gold case inspired by 19th-century savonette pocket watches. The case measures 44 mm across and features a convex crystal, screwed lugs, and a blend of polished and brushed finishes. The dial reveals the signature dual-gear-train architecture of the Duomètre concept, with a triangular layout that separates the timekeeping and calendar functions. The left side is partially open to showcase the rotating Heliotourbillon, while the right side features an opaline-finished perpetual calendar display with grande date, day, month, year indication, and moon phase. The manually wound 388 beats at a frequency of 28,800 vibrations per hour and delivers a 46-hour power reserve. It comprises 655 components, including 89 jewels, and integrates separate barrels and gear trains for timekeeping and complications. The Heliotourbillon mechanism consists of 163 components and rotates on three axes.

CHRONO 10:10 did an excellent job indeed. From the feedback to the purchase offer that was given within the hour on a Sunday to the updates regarding the shipment - the service was spot on all the way. The watch arrived in less than 24 hours after being sent (Destination: Germany) and was packed up very diligently with bonus items added. A small misunderstanding was handled very professionally and the costs were kindly covered by CHRONO 10:10 - no questions asked.
