A museum-quality silver compass ring, crafted in Paris between 1845 and 1862. Smartly constructed and imposing in scale, this striking piece features a compass crafted by Swiss clockmaker Jean Henry Blatter (Mogelsberg, Switzerland/CH,1803 - Neuilly Sur Seine, France, 1874) and a setting by French silversmith Pierre Longpré (Blennes, France, 1806 - Vincennes, France, 1862).
Blatter patented this design in 1845 at 16 rue Bourg-l’Abbé, Paris. Outside of museum collections and reference books, this is the only example we have ever encountered. The ring bears a proper hallmark for Longpré on the back. (see the photos)
Considering its nearly 180-year history, the compass remains operational, and the ring itself is in remarkably fine condition. Statement-making and versatile, it can be worn on the finger or suspended from a chain as a pendant—a meaningful talisman for anyone embarking on a new venture.
