Jaeger-LeCoultre introduced the Duometre Heliotourbillon Perpetual in full platinum, limited to 20 pieces. There are four notable points of the watch: 1) a new platinum bracelet was made for this watch; 2) the watch features the Heliotourbillon, which is a triple-axis tourbillon; 3) the watch also has a perpetual calendar with a grande date display; and 4) the watch features JLC’s patented Duometre which has two barrels and two separate gear trains housed in a single calibre and linked to a single regulating organ. One gear train powers the time indications and the other drives all additional functions. To summarize: the watch is a masterpiece.
