The Récital 20 Astérium® seamlessly continues the tradition set by its illustrious predecessor, reprising the characteristic shaped case to present an unprecedented mechanical display that showcases the volumes and decoration of the timepiece. Despite its complexity, setting this timepiece is as quick and easy as for a timepiece with a simple calendar mechanism. The same applies when determining the position of the stars in the sky. To do this, simply point the arrow of the sky map hand northwards. The ellipse opened by this sky map hand outlines the part of the sky that is visible from the wearer’s position at the moment of observation, assuming that the observer is positioned in the center of the elliptical window and enjoys a 360° view.
