Delivered with a photocopy of Swiss Patent No. 11948 of 20 March 1896.
The present watch is one of the exceedingly few carillon minute repeating watches with Westminster chime on four hammers. It is fitted with Constant Piguet's patented system for a repeating-carillon watch with four hammers onto four gongs, Swiss Patent No. 11948 of 20 March 1896, for which the talented watchmaker of Le Sentier is perhaps best known. His patent comprised a repeating watch striking the quarter hours by means of four hammers onto four gongs, each of a different sound. The carillon of this watch strikes the Westminster chime.
The present watch is furthermore distinguished by its very good and crisp overall condition.
