A sophisticated luxury timepiece from Longines, the Master Collection Chronograph Moonphase features a classic white guilloché dial with Roman numerals, three subdials (chronograph minutes, chronograph hours, and moonphase with date), and an annual calendar complication showing year (e.g., '2020'), month ('SEP'), and day. The watch boasts a two-tone stainless steel and yellow gold case and bracelet, blue hands for high contrast, and a sapphire crystal. Powered by an automatic mechanical movement (Caliber L678 or similar), it offers precise timekeeping with 30m water resistance. The elegant design balances complexity and readability, making it ideal for formal events, business settings, or refined everyday wear. The integrated bracelet with brushed and polished finishes enhances comfort and luxury appeal. Crafted in Switzerland, it exemplifies Longines’ heritage of precision and elegance since 1832.
