This watch is not only a chronograph but a dual timer. The second time zone is read by means of a filigree-style second hour hand on the central dial. This is supplement by a day/night indicator appearing through a window just below the Jaeger-LeCoultre signature on the dial. The chronograph hour and minute counters are positioned at 9 and 3 o’clock, while the small seconds dial appears at 6 o’clock. The case is made of high-tech ceramic, and it is fitted with Jaeger-LeCoultre’s patented compression key crown guaranteeing optimal water resistance to 100 meters. The watch contains automatic Caliber 757, and is issued in a 500-piece limited edition.
