Tsar Alexander III presented the egg to his wife, the Czarina Maria Feodorovna.
The egg is made of varicoloured gold, diamonds, translucent royal blue and opalescent white enamel.
This egg was designed as a clock in the Sevres tradition. It's a good example of the quatre couler technique. A diamond-set serpent is coiled around the shaft supporting the egg. The head and tongue point to the hour.
The egg is similar to the "Duchess of Marlborough Egg" (ca. 1902). This is interesting because Faberge had a rule of not repeating a design.
As a clock egg, it had no surprise.
