Jaeger-LeCoultre «Reverso Répétition Minutes» BASEL 94
«Reverso Répétition Minutes» is a minute repeater, one of the most challenging complex mechanisms a watchmaker will ever build, and an exceptionally fascinating one. The difficulties involved didn’t stop JaegerLeCoultre from ordering a full 500 of them, each individually numbered, from its team of talented master watchmakers. Finished and assembled by hand, these movements comprise no less than 306 separate parts and their minute repeater device is ingeniously dissociated from the basic timekeeping mechanism. The minute repeater sounds the time to the exact minute in a melodious musical code. When the slide bolt located on the case flank is actioned, two small hammers strike a pair of gongs (in specially treated steel made exclusively for Jaeger-LeCoultre), placed along the inside flank of their 18K rose gold Reverso case. The hours are struck on the lower pitched gong, the quarters on both and the minutes on the higher pitched gong. The 38-jewel extra-thin movement has a high-frequency (21,600 v.p.h.) beat and provides up to 32 hours of power reserve.
