The Longines Master Collection Chronograph Moonphase is a sophisticated Swiss-made automatic timepiece featuring a silver-white guilloché dial with applied Arabic numerals, blue steel hands, and three subdials: date (with year indication '2022'), day-month (showing 'DEC'), and moonphase. The watch combines stainless steel case with 18K gold bezel and crown, offering elegant two-tone contrast. It includes chronograph functionality (30-minute and 12-hour counters), perpetual calendar complication, and a moonphase display with realistic lunar disc. The brown alligator leather strap with white stitching enhances its classic luxury appeal. Powered by the L688 automatic movement (based on ETA A05.L01), it offers approximately 54 hours of power reserve. Ideal for formal business settings, evening events, or refined daily wear, this watch exemplifies Longines’ heritage of precision and elegance since 1832. Its balanced 42mm diameter suits most men’s wrists, while the sapphire crystal ensures scratch resistance and clarity.
