This nocturnal watch --horologium nocturnale, noctilabium- is an astronomical instrument used to measure the time through the observation of the Pole Star and the position of bright stars in the celestial sphere.

This nocturnal is a reproduction of the one made in 1570 by Girolamo della Volpaia (History of Science Museum of Florence). Because it was made before the Gregorian reform (1582) and its creator had not very accurate calculation boards, to use this instrument correctly one must add 38 days to observation date.
