Description

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.

CHRONO 10:10 did an excellent job indeed. From the feedback to the purchase offer that was given within the hour on a Sunday to the updates regarding the shipment - the service was spot on all the way. The watch arrived in less than 24 hours after being sent (Destination: Germany) and was packed up very diligently with bonus items added. A small misunderstanding was handled very professionally and the costs were kindly covered by CHRONO 10:10 - no questions asked.
