The third egg, from 1887, was the "Blue Serpent Clock Egg".
This is the first of the Imperial Fabergé eggs to feature a clock - the rotating white band with roman numerals that encircles the egg - enameled in translucent blue. The diamond set snake coiling around the base points at the hour with it's head. The three panels with raised motifs in quatre couleurs on the pedestal, represents the arts and sciences. Since the clockwork is hidden inside the egg, it doesn't contain the usual "surprise".
The current owner of this egg is Prince Albert II of Monaco.
