The Master Control Chronograph Calendar revives the emblematic codes of the signature collection: round case, curved lugs, double polished and satin finished surfaces, Dauphine hands, appliqué hour-markers, Jaeger-LeCoultre logo and signature. This timepiece displays a calendar, chronograph and moon phase, and features two different straps – a new interchangeability system allows the wearer to switch, depending on the circumstances, from a casual style to a more sophisticated look. The look of the watch changes depending on whether you choose the stainless-steel strap or the Novonappa calfskin strap with folding clasp. A simple push of a double button located between the lugs of the case is enough to effortlessly change the strap. No matter which strap is chosen, elegance is a certainty on the wearer’s wrist.
