The Jules Audemars collection pays homage to one of the two founding fathers of the manufacture, a true pioneer in the field of complications, and embodies Audemars Piguet’s traditional values. The level of finish is what makes the difference, over and above the technical complexity and reliability. Designing a supremely comfortable and aesthetically pleasing case is an art in itself, involving a highly technical production process. Audemars Piguet 26390OR.OO.D093CR.01 Jules Audemars features a Perpetual Calendar Movement, which takes account of monthly variations including those of leap years, and moon phase, a complication which depicts the evolution of the moon as seen from the earth. The elegant and sophisticated case is presented in 18K Rose Gold, which matches the bezel also in 18K Rose Gold. This Watch features a Scratch-Resistant Sapphire crystal, and has a Brown dial, and very well organized: Date sub-dial at the 3 o'clock position. Day of the week sub-dial at the 9 o'clock position.
