Longines Watch PrimaLuna Ladies L8.122.4.99.6. A silvery moon on a spring night; a star that glistens reaches its peak and then disappears. A symbol of passing time, living time and the moon that entrances us with its rounded, delicate lines the Longines PrimaLuna is a tribute to this silvery star. Its soft silhouette is enhanced by the exquisite purity of the dial and the whole is illuminated by a play of sparkling diamonds.
