Used Jaeger LeCoultre Master Control Chronograph Calendar Q4138420 Silver Dial

Description: Jaeger LeCoultre Master Control Chronograph Calendar Q4138420 Pre-owned Jaeger LeCoultre Master Control Chronograph Calendar ref Q4138420 (2022) is one of the most technically interesting releases from the brand in recent years. When it debuted in 2020, it introduced something JLC had never combined before: a full chronograph paired with a triple calendar and moon phase in a single watch. The result is a complication-packed timepiece that still feels remarkably balanced on the dial. Housed in a 40mm stainless steel case inspired by JLC’s classic mid-century designs, the watch features a clean tri-compax chronograph layout with day and month apertures at 12 o’clock and a moon phase integrated into the date display at 6. A pulsation scale around the dial adds a subtle vintage medical chronograph touch. Inside beats the in-house caliber 759, a column-wheel chronograph with vertical clutch and a 65-hour power reserve, visible through the sapphire caseback. Like all Master Control models, it undergoes Jaeger-LeCoultre’s rigorous 1,000 Hours Control testing before leaving the manufacture.
