This table clock-egg is made in the Louis XVI style, and it is covered in translucent strawberry-pink enamel, and decorated with gold laurel swags. The egg is held up by three pilasters with gold lion paws. The opaque white enameled, revolving dial is set with diamond-set Roman numerals. Around the upper half of the egg coils a gold snake, which arrow-shaped tongue shows the hour.
Hanging in the laurel swags are three oval medallions. Once these contained miniature portraits of Prince Felix Youssoupov and his sons, Felix and Nicholas. Now though, these have been replaced with the initials of the egg's last owner, Maurice Sandoz - M, Y, and S - in gold.
The egg was given by Prince Felix to his wife, Zenaïde, on the occasion of their 25th wedding anniversary. Since 1995 the "Youssoupouv Egg" has been in the Fondation Edouard et Maurice Sandoz, in Lausanne, Switzerland.
