The 580P automatic mechanical movement stands out with its extremely precise large astronomical moon which only varies by one day every 122 years. With its understated, pure design, the 580P caliber displays the hours and minutes in the center as well as the moon phases in a large opening at 12 o'clock. It is also fitted with an oscillating weight decorated with white or black coat-of-arms, depending on the version, and a balance stop. Traditional decorations, circular Côtes de Genève, circular-grained mainplate, beveled bridges and blued screws complete this reliable and robust movement, while featuring the distinctive Piaget touches.
