Master Control Q4018421

The art of watchmaking in one of its purest expressions... This is what characterizes the Master Control Date. A model made from the purest stainless steel, which opens a new page in the history of the Master Control collection by Jaeger-LeCoultre. Setting a benchmark in fine watchmaking, this collection reinterprets the emblematic round shape of wristwatches that was so popular in the 1950s. Among the major changes made to the entire collection: A caliber offering a 70-hour power reserve, a new 40-mm case with a double polished and satin finish on the side, and a new Novonappa® calfskin strap.
