I just know that the (now closed) Musée d’Horlogerie de la Vallée de Joux used to have the Hector Audemars watch and described it as the first of its kind, also listing the later systems developped by Adrien Philippe (1942), Adolphe Nicole (1846), and Antoine LeCoultre (1947), which I believe is the first one to have the combined winding and setting system located on the dial side as we know it mostly today
