Jacques Bruguier Tortoiseshell Singing Bird Box With Gold Stitching

Very rare singing bird box by Jacques Bruguier, made in Geneva circa 1850.
When the mechanism is activated, the lid opens and a small, beautifully detailed bird emerges from a finely engraved and openwork grille. The bird sings a lively tune while turning its head, flapping its wings and tail, and opening its beak.
The fusee mechanism is a masterpiece of engineering, highly sought after by collectors worldwide.
Jacques Bruguier is one of the greatest names in 19th-century Swiss clock and automaton design. The tortoiseshell box is in exceptional condition, adorned with delicate gold inlaid (“piqué”) motifs on the lid. The painted enamel shows a colorful, lively bird in a refined setting.
The box is accompanied by its original case (as is) and a key.
An exceptional piece for any discerning collector.
