Genuine original movement, outshining all counterfeit products on the market. The original factory movement number is L296, and the model is Swiss E63.171, not the modified movements starting with F that are used in the market. The Longines Heart Moon series moon phase watch is equipped with the L296 quartz movement, with a case diameter of 30.5 mm. The silver lacquered Roman numeral dial beautifully complements the blued steel hands. The dial displays hours, minutes, and seconds, with a date display window at the 3 o'clock position and a moon phase display at the 6 o'clock position, following the lunar cycle with the full moon on the 15th day of the lunar calendar. It comes with a stainless steel bracelet and has a water resistance of up to 3 bar.
