Вох in rectangular silver case. Top and lateral sides are covered with light-blue enamel over guilloched surface. Each panel is framed by chased silver border with floral ornament. An oval lid with the painted image of Rousseau island and Mont Blanc bridge in Geneva in chased frame. Bouquet of roses on turquoise background  is on the lid inner surface. White enamel clock dial with two hands, Arabic numerals and minutes graduations is in the center of the front panel. It is decorated with a chased frame. A sliding lever for switching the movement on is on the right side of the case. The key for winding the bird and the crown for winding the clock are in the bottom. The inscriptions «SWISS" and "STERLING SILVER", the numbers and hallmarks are stamped on the bottom. The oval lid opens automatically during the operation of the movement and a tiny bird in painted feathers appears. It spins, flaps its wings and tail, turns the head, opens and closes the beak; the sound movement imitates bird's chirping. On completion of the movement's work the bird hides under the guilded engraved openwork lattice and the lid descends. The housing is covered with green embossed leather.
