INSTRUCTION FOR USE ASTRONOMY AS A TIME MEASUREMENT INSTRUMENT The measurement of time finds its origins in the observation of astronomical phenomena such as the motions of celestial bodies in the sky. Most of the calendars have been developed according to the movements of the Sun as Man observed a regular alternation of diurnal and nocturnal periods of time.

A CELESTIAL GLOBE INDICATING THE CONSTELLATIONS OF THE ZODIAC The celestial globe of Cosmos, whose mechanism is based on the duration of a sidereal day, is an astronomical globe indicating the constellations of the Zodiac. It is composed of 12 constellations which showcase their very own combination of stars.

SETTING MECHANISM The setting mechanism features an exclusive system developed by Girard-Perregaux’s R&D department. Instead of relying on a traditional crown on the case side, the setting system is based on four rotating bows, called “bélières”, placed at the back of the timepiece.

TRIPLE FOLDING BUCKLE OPENING In order to provide an easy access to the setting mechanism, the triple folding buckle is removable thanks to an opening system. First, open the triple folding buckle by pressing on both push-buttons number 1, then, open the security system by pressing on both push-buttons number 2. Warning: After finishing the setting, make sure to secure the buckle again by replacing, from above, the unleashed part in its original position.
WINDING The winding bélière is placed at the back of the watch at the bottom center. Manual-winding: Your watch requires regular winding to work normally. To wind, pull the bélière up and turn it clockwise 11 times for a full winding. Once the watch is wound up, push the bélière down to its original position.

SETTING THE ZODIAC CONSTELLATIONS INDICATOR The Zodiac constellations setting bélière is placed at the back of the watch on the right-hand side. Warning: Before making any setting, set the time at 12 o’clock. For a better accuracy, set the time at 12 o’clock solar time as it coincides with the time when the Earth and the Sun are aligned with the current constellation.
