In the mechanisms, the record shows Chopard Happy Sport Ladies Watch 27/8238-23 that two moons comprises 59 teeth. Driven by an excellent rotation every 24 hours, makes a half turn in 28 days and 12 hours. In comparison with the actual lunar cycle (29 days, 12 hours, 44 minutes and 2.8 seconds), the screen thus accumulates a difference of 44 minutes per lunar cycle, ie, 8.81 hours per year. The more complex and precise astronomical moon phase mechanism Athys the 2134 Luna is composed of three sets of wheels and pinion. The first makes a complete rotation in 24 hours, the second driving in 7 days, which in turn drives the 135-tooth moon disk. The latter half full Chopard Happy Sport Ladies Watch 27/8238-23 back in 29 days, 12 hours and 45 minutes, which means that the relative error is -0.02 hours or 12 minutes per year.
