Product Details
The True Moon timepiece features the world's first mechanism capable of providing a realistic view of the phases of the moon as we see them in the northern hemisphere with a deviation of just one day in 125 years. This unprecedented feat was achieved by using the synodic month of 29 days, 12 hours and 44 minutes - the time between successive recurrences of the same phase - as a basis for calculation.
