The Audemars Piguet Royal Oak Perpetual Calendar Ultra-Thin Watch, despite its long name, is actually the slimmest perpetual calendar watch in the world. This ultra-thin premium timepiece features a titanium and platinum case that’s only a mere 6.3 millimeters thick. The high-quality case material meets the precisely-tuned Calibre 5133 automatic movement, which is also extremely thin at only 2.89 millimeters thick. The watch features the classic day/date display, along with a moon and month display, leap year, and a day/night indicator. The perfectly matched titanium watch band complements an already spectacularly designed multifunctional automatic watch. Overall, Audemars Piguet didn’t overlook a single detail in the design of this beautiful timepiece.
