Watches with a carillon minute repeating mechanism are an extremely rare find; there are only very few pieces known today that have Westminster chimes or four hammers. The design was patented as patent No. 11948 on March 20, 1896, by Constant Piguet. The two other makers who were known to have specialized in this type of watch were Eduard JeanRichard and Victorin Piguet and to the best of our knowledge only three tunes were played by the four hammer carillons Westminster chimes, the Swiss National anthem and God Save the King.
