The watch comes with a unique key, set with jewels, probably Russian. The watch is technically a masterpiece of the watchmaker’s art. The engraved coat of arms and the unusual key, indicate that the watch was probably made for the Russian Empire. Pocket watches with Grande Sonnerie are the greatest rarities among watches with striking movements. They are the most complicated early chiming movements ever!
