Description

The Jaeger-LeCoultre Master Grande Tradition Q5246508 debuted in 2025. This version is crafted in platinum, with a case measuring 42mm in diameter and 13.27mm in thickness. The bezel is set with baguette-cut diamonds totaling approximately 3.4 carats. The blue sunray dial is built on two levels with contrasting finishes to emphasize depth. Indications include a perpetual calendar with sub-dials for day, date, month, and year, along with a moon phase with day/night display at 9 o’clock. At 6 o’clock, the cylindrical balance spring tourbillon doubles as the small seconds. The watch is powered by the automatic caliber 985. This movement consists of 431 components, including a tourbillon of 83 parts weighing less than 0.4 grams. It beats at 28,800 vph (4 Hz), has 49 jewels, a single barrel, and a power reserve of 45 hours. The case is completed with a sapphire crystal front and back and is water resistant to 50 meters.

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.
