About this watch
The Jaeger-LeCoultre Master Control Chronograph Calendar Q4138431 debuted in 2025. This watch pairs a triple calendar with chronograph functionality in a stainless steel case measuring 40 mm in diameter and approximately 12.05 mm in height. The silvered sunray-brushed dial displays the date via a pointer, with apertures for the day and month below 12 o’clock, and a moon phase at 6. A pulsometer scale encircles the dial periphery.
Inside ticks the automatic caliber 759, which is visible through the sapphire case back. This in-house movement features a column-wheel chronograph mechanism, calendar, and moon phase, with a power reserve of 65 hours. The watch is delivered on a light brown calfskin strap and is supplied with an additional black alligator leather strap.
