About this watch

The Longines Master Collection 40 Moonphase is a masterpiece of watchmaking, blending traditional elegance with modern innovation. Its stunning design features a round stainless steel case, measuring 40mm in diameter, with a silver guilloche dial and Arabic numerals. The moonphase complication at 6 o'clock adds a celestial touch, while the Feuille hands gliding over the dial lend a graceful touch. At its heart lies the Longines caliber L899.2, an automatic movement boasting a 64-hour power reserve and 21 jewels for precision. The watch comes with a stainless-steel bracelet that complements the overall look, making it ideal for daily wear. With a water resistance of 30 meters, this watch is perfect for everyday adventures, but not designed for swimming or diving.
