Jaeger-LeCoultre Master Calendar Q4148420 Watch

With the new Master Control Calendar, the moon phase offers a horological complication, a jumping date, which flies between the 15th and 16th day of the month. This new mechanism ensures you never lose sight of the moon phase. In its stainless steel version perfectly matched with its sunray silver dial, the watch offers a complete calendar. With a sapphire crystal case back, the reverse of the watch reveals the components of its new generation calibre, which promises a 70-hour power reserve.
