The launch of the Master Grande Tradition Gyrotourbillon Westminster Perpétuel by Jaeger-LeCoultre at the SIHH 2019 marked the “Grande Maison” return to the grand complication. The watchmaker is continuing with the ultra-complication theme by introducing its latest creation, the Master Grande Tradition Répétition Minutes Perpétuelle. The highly complicated timepiece has a stunning combination of a perpetual calendar and minute repeater augmented by an extremely detailed and novel construction. Starting with the case of the watch, it is in 18k white gold and measures 43mm wide and just 13.72mm high, which is surprisingly thin for a minute repeater. What makes is stand out is that the case is highly detailed, made of 80 hand-finished components, including separate lugs. All the different components are finished in contrasting treatments, including polished tops; recessed, sandblasted flanks; and a polished convex bezel.
The Master Grande Tradition Repetition Minutes Perpetuelle is powered with a brand-new movement, the caliber 950. The self-winding caliber has a power reserve of 38 hours. In addition to the perpetual calendar, an entirely novel gong configuration was created to optimize the acoustical qualities of its minute repeater. Replicating the richness and strength of antique sonnerie pocket watches, the new configuration elongates the gong and loops it around the entire height of the case to produce greater resonance. The new timepiece is a lot more than its novel chiming mechanism. It comes with the most advanced type of calendar, a perpetual calendar module. The indications are spread over 3 sub-dials, with the date at 3 o’clock, the month at 6 o’clock, the day of the week and moon phase at 9 o’clock, and a full-year indication on 4 digits sandwiched between 7 and 8 o’clock. The timepiece is available with either a blue flinqué enamel dial or plainer silver grained dial, priced, priced at €240,000 (about $268,000) and €225,000 (about $251,000), respectively. Each version is limited to just 30 examples.
