For this new execution of the Chapter Three, special attention was given to the color of the dial. The deep black color emphasizes the classical esthetic of the watch and the beauty of the guilloche finish. This new dial complements the choice of the existing silver and anthracite versions.
The ingenious mechanism of the opening of the dial becomes the DNA of the Chapter Three. A pusher on the center of the crown allows to lower two concealed dial panels of the dial in order to reveal two additional and hidden time indications: a second time zone indication (also known as GMT) and a Day/Night indicator, both displayed on cylinders, the signature feature of Maîtres du Temps – Atelier d’Horlogerie.
The opening and closing mechanism is a complication in itself. When the dial is closed a light pressure on the pusher in the crown lowers the panels below the level of the dial, and then releasing the pusher the same disappears below the dial unveiling the cylinders of the second time zone and the Day/Night indicator. A new pressure of the pusher creates an inverted rotation of the panels and resets them in the initial position before making them rise flush with the dial when releasing the pusher.
