A sophisticated luxury timepiece from Longines' iconic Master Collection, featuring a black guilloché dial with Roman numerals, three subdials (chronograph minutes, chronograph hours, and moonphase), and an annual calendar displaying year (2024) and month (OCT). The watch combines stainless steel and 18K gold elements—gold bezel, crown, and pushers—creating a refined two-tone aesthetic. Powered by an automatic mechanical movement (Caliber L678 or similar), it offers precision chronometry with a 42mm case, sapphire crystal, and water resistance to 30m. The black alligator leather strap with white stitching enhances elegance and comfort. Ideal for formal events, business settings, or discerning collectors seeking horological complexity and Swiss craftsmanship. The moonphase complication adds poetic charm, while the annual calendar reduces adjustment frequency to once per year. Crafted in Switzerland with meticulous attention to detail, this watch exemplifies Longines’ heritage of elegance and technical excellence.
