Within its 18-carat rose gold case, the L.U.C Lunar Big Date timepiece exudes a captivating poetry. The moon phase complication of the chronometer-certified movement is so accurate that the difference between the actual lunar cycle and its indication is just one day every 122 years. The grey dial displays a large date at 12 o'clock and an original view of the moon phases showing both Northern and Southern hemispheres.
