Jaeger-LeCoultre Master Calendar 1558420 OM Factory Silver Dial Replica Watch. The lid-shaped silvery sun dial, seen from the side, has a quiet radian and has been repeatedly modified to ensure that its verve is comparable to that of the original. The placement directions of the above useful functions are orderly. The toffee-shaped central pointer shows hours and minutes. The most attractive thing is to appreciate the brand-new date showing at the end of the long pointer. The pointer is decorated with a new moon and quietly sweeps across the progressive scale consisting of 1 to 31 arranged on the periphery of the dial. The two windows of the watch at 12 o’clock show the week and the month separately, the sub-dial at 6 o’clock shows the month, and the marginal position shows the second. According to tradition, the moon phase appears between two clouds and then rises to the starry sky. The wearer is believed to be intoxicated by these geographical wonders. Swiss Jaeger-LeCoultre caliber866/1 automatic movement has excellent comprehensive performance.
