At the 1992 World Watch, Clock and Jewellery Show, Philippe Dufour was awarded a gold medal for his «Grande et Petite Sonnerie Répétition Minute». Only four examples of this timepiece have ever been made, all of them acquired by one avid watch connoisseur. This superb collectors’ piece rings the hours and quarters automatically and, by simply pressing on a push-piece, will ring the hours, quarters and minutes.
