A pre-SIHH premiere from Jaeger-LeCoultre, which the international press (including one of our correspondents, of course) will be able to see and touch in real life tomorrow.
This is the House's 2007 complication, which this year has ventured into the chronograph complication. New collection, then, and new movement!
The Duomètre à chronographe is a single-pusher chronograph (pusher on two, pictured) with a foudroyante hand at 1/6th of a second (the hand makes one revolution of the small square in 1/6th of a second jumps). Naturally, the movement is new. Named Calibre 380, it is equipped with two independent barrels: one for the time display (hours, minutes, seconds) and one for the chronograph. In this way, activating the chronograph, despite the presence of the foudroyante hand, in no way affects the autonomy and precision of the time base.
The chronograph counters are concentric (but wasn't the first monocounter, the one by Patek Philippe, considered ugly? Now there are already two other companies offering this: Jaeger and IWC), placed at three o'clock: hours and minutes, plus a small window indicating only the minute units (e.g. 2 minutes, when the large counter indicates 32)...
The 380 calibre is equipped with a large balance, oscillating at 21,600 vibrations per hour (hence, six clicks of the foudroyante hand per second, positioned at six o'clock).
