Cartier’s ultra-complicated models, such as this year’s Grand Complication, have garnered much of the watch industry spotlight in recent years, but not to be overlooked is the Cartier Rotonde de Cartier Perpetual Calendar Chronograph, introduced at SIHH 2015, the first timepiece in the Rotonde de Cartier family to combine these two popular complications.

The watch, which comes in a 42-mm-diameter case of rose gold (pictured) or white gold, is powered by cartier replica watches automatic manufacture caliber 9423 MC, which includes a new, in-house, dial-side module for the perpetual calendar functions. The calendar mechanism, which is designed to compensate for the irregularities of the Gregorian calendar, such as 30- and 31-day months and leap years, is a complex system of snails and cams that has at its heart a wheel that completes one revolution every four years. The wheel has 48 indentations of various depths on its circumference that indicate, via a feeler, the length of the current month. A retrograde hand, mounted on the dial at 6 o’clock, indicates the days of the week, and another center-mounted hand indicates the cheap cartier replica date by pointing at the numerals 1 through 31 along the edge of the dial.

The dial features openworked areas and guilloché and sunray patterns, both Roman and Arabic numerals, and sword-shaped (for the hours and minutes) and hammer-shaped (for the date and day) hands in blued steel. The caseback features a sapphire window offering a view of the movement. The beaded gold crown is accented by a sapphire cabochon. The fake cartier comes on a black or brown alligator strap with a gold double-adjustable folding clasp.
