For this year’s first-ever digital version of the Watches & Wonders salon, Jaeger-LeCoultre put the spotlight on its Master Control collection, so named for the intensive (and exclusive) “1,000 Hours” battery of in-house tests that each timepiece undergoes before it reaches the market. Headlining this year’s new models is a timepiece with an all-new in-house movement that combines a chronograph, a triple calendar, and a moon-phase. Here’s a rundown of the Master Control Chronograph Calendar.

Jaeger-LeCoultre’s Master Control Chronograph Calendar combines three complications.

The aforementioned trio of complications, which are derived from the newly developed Caliber 759, are brought together here for the first time in a Jaeger-LeCoultre timepiece.

Surrounding the silvered sunray dial, with its faceted hands and applied wedge indices, is a flange emblazoned with a vintage-style pulsometer scale.
