Jaeger-LeCoultre Master Control Chronograph Calendar Q4138420

This was a first for Jaeger-LeCoultre: the Master Control Chronograph Calendar, launched in 2020, combined a full triple calendar with an automatic chronograph in one dial. The 40mm steel case stays classically restrained, and the silver sunray dial packs in a lot without clutter, day and month windows beneath the logo, a combined moon-phase and pointer date at 6, running seconds at 9, the 30-minute chronograph counter at 3, a blued central chronograph hand, and a pulsometric scale around the edge. Driving it is the Calibre 759, a 356-part column-wheel chronograph with vertical clutch and a 65-hour reserve, visible through the display back over a pink gold rotor. Water resistance is 50m. It wears on a leather strap with a steel folding clasp and comes with box and papers, joining the Jaeger-LeCoultre Watches at Grand Caliber as one of the more quietly complicated dress chronographs around.
