Jaeger-LeCoultre Q4148421 description
The Jaeger-LeCoultre Master Control Calendar Q4148421 debuted in 2025. It features a stainless steel case measuring 40mm in diameter and 10.95mm in height, paired with a silvered grey sunray dial and dauphine-style hands. The calendar layout includes day and month apertures below 12 o’clock, a central date hand with a jumping mechanism that skips the 16th to avoid obscuring the moon phase aperture at 6 o’clock.
This watch is powered by the automatic 866AA, which offers hours, minutes, moon phase, full calendar, and central date with jumping hand. It has a power reserve of 70 hours and beats at a frequency of 28,800 vph. The movement is visible through a sapphire crystal case back. The watch is delivered with a light brown calfskin strap and an additional black alligator leather strap, both equipped with a stainless steel folding clasp.
