Jaeger-LeCoultre Master Moon Phase Series, with a case diameter of 39mm for men and 34mm for women, thickness of 9.9mm, perfectly synchronized with the original. The sub-dial at six o'clock displays both the solar and lunar calendars, and features a moon phase and dual date display. The moon phase completes a full rotation every month, with functions that are identical to the authentic model. The moon phase dial features a 3D metal moon phase. The movement is a replica of the Cal. 925/1 integrated movement, fully synchronized with the original in-house movement. We remain true to our original intention; each movement undergoes a series of rigorous testing and selection before leaving the factory. Please recognize our exclusive quality.
