Chronoswiss Perpetual Calendar CH 1720 Watch Line
The many functions of a perpetual calendar complication are neatly laid out on the dial using three subsidiary dials and one aperture window that features the moonphase. Notice that the top subdial used to display the month is set out to display the months for a total of four years. The reason for this is to indicate if the current year is a leap year which adds a day to February. A perpetual calendar is defined as one that is able to compensate for leap years and thus only rarely needs adjusting (that is unless you forget to wind it).
Like most Chronoswiss watches, the "onion" crown is larger than you'd expect for the watch size, but allows for comfortable winding of the movement. The layout design is perfect from a legibility standpoint with the blued steel hands being the perfect width and length. The case is available in five different materials: there is a limited edition platinum model, a steel model, and 18k yellow, rose, or white gold models. The dial face is a machine polished sterling silver in an off-white color finish. Securing the watch is an alligator strap. I'd have to say that this is one of the most desirable Chronoswiss watches I've seen in a while, with flawless execution of the Roman numeral hour markers, and a sublimely attractive yet simple design.
