About the Jaeger-LeCoultre Q4148450
The Jaeger-LeCoultre Master Control Calendar Q4148450 debuted in 2025 as a limited edition of 500 pieces. Its stainless steel case measures 40.0 mm across and 10.95 mm in height, framing a two-tone grey grained dial. The layout features day and month apertures beneath 12 o’clock, a small seconds at 6 o’clock incorporating the moon-phase, and a peripheral date display indicated by a red-tipped hand. In order not to obscure the moon-phase, the date hand makes a jumping glide between the 15th and 16th of each month. Additional dial elements include faceted Dauphine hands, triangular applied markers, and Arabic numerals at 12, 3, and 9.
Inside ticks the self-winding Calibre 866, providing displays for hours, minutes, seconds, complete calendar, and moon-phase. The movement runs at 28,800 vph and offers a 70-hour power reserve. Water resistance is set at 5 bar. The watch is delivered on a black calfskin strap with an interchangeable double folding clasp.
