The Portuguese Grande Complication watch, known as Reference 3774, is a true masterpiece of watchmaking. It showcases impressive features such as a perpetual calendar that can accurately keep track of dates until the year 2499, a moon phase display that never needs adjustment, and a chronograph for precise timekeeping. The minute repeater function, activated by a slide, plays a beautiful melody to announce the exact time. This watch is truly a remarkable achievement in luxury watch craftsmanship.
