Movement of the Sauterelle à Lune Perpétuelle by Andreas Strehler

Blood Moons, Lunar Tetrads, And The Andreas Strehler Sauterelle À Lune Perpétuelle

The Andreas Strehler Sauterelle à Lune Perpétuelle contains a moon phase mechanism that will only need adjustment by one full day every 14,189.538 years. And not only does the Lune Perpétuelle have an extremely accurate moon phase, but with the help of the constant force mechanism it is even more accurate for the little intervals as well.
