Jaeger-LeCoultre's Master Control Calendar

Jaeger-LeCoultre's Master Control might not be the watchmaker's oldest collection, but it's one of its most timeless. Launched in 1992, Master Control has remained popular thanks to its modern features (a silicon escapement; an extended power reserve, etc) and clean design, which is inspired by the round watches popularised in the '50s that—let's face it—go with anything and everything.
For Watches & Wonders 2020, the watchmaker added a new pink gold alloy to the collection, dubbed Le Grand Rose gold, and has upped each watch's power reserve to a convenient 70 hours.
