In 1857 he turned his attention to navigational instruments and begun making marine bearing compasses for the U.S.Navy before the American civil war. At the time the British admiralty dry mounted nautical compasses were considered by all navies and commercial shipping companies as the highest technological standard of the day, however, in 1860 Ritchie had received a US patent for the first successful and practical liquid-filled marine compass for general use.

The bezel surrounding the grille through which the bird pops up and down is also of gold. The underside of the lid is also beautifully painted with a posie of flowers on a light blue background. The bird, typically for Rochat, is of a large size for a singing bird box and the grille is typical of Rochat's work rather than Bruguier's. The top of the case with a fine border made from gold.

On completion of his 20 second performance he drops through the superbly pierced silver gilt grille and the lid closes after him. All fusee movements allow the bird a longer performance than the later spring barrel movements but more importantly one extra manipulation, the movement of the head from left to right.
