Philippe Dufour Grande And Petite Sonnerie
This was where it all began. After developing a series of grande sonnerie pocket watch movements for Audemars Piguet, Dufour decided it was time to make his name known and started his eponymous brand. His first watch wound up being a scaled-down version of those grande sonnerie movements, and became the first ever grande (and petite) sonnerie wristwatch.
