Ronda Harley Quartz

European Watch Clock and Jewellery Fair 1985 BF 309
Ronda is introducing at BASEL 85 its new quartz movement 3878 with moon phases, 8 3/4 lines. Here a lady’s model (ø 2/4 mm) equipped with this movement. The large dial aperture displays a moon against the backdrop of a starry night sky. Lunar cycle at noon. Perfect synchronization with the lunar cycle of 29 1/2 days. The moon phase is, however, quickly correctable, if necessary. (RONDA Harley Quartz)
