Carillon minute repeating watches are very rare, only a few are known with Westminster chimes. On March 20, 1896, Constant Piguet patented this system of minute-repeat with carillon, under the No. 11948. The makers that specialized in this type of watch were Constant Piguet, Eduard JeanRichard, and Victorin Piguet. The known tunes played by four hammer carillons are: Westminster chimes, the Swiss National anthem, and God Save the King.
