Made by Philippe Dufour, this Grande et Petite Sonnerie
is amongst the most significant wristwatches ever made. With the initial piece requiring over two and a half years to complete, it became the first wristwatch to house the impressive chiming complication. Only eight examples have ever been made, with this one being the third to leave the watchmaker’s workshop, and unique in its configuration. Completed in 1995, it was first delivered to the Sultan of Brunei.
