Over his lifetime, Salomons amassed the world's largest private Breguet collection, which ultimately grew to 124 pieces, including what are considered to be the two greatest examples of Breguet's watchmaking work – the "Marie Antionette" and the double-faced "Duc de Praslin" watches. In 1924 Salomons donated the "Duc de Praslin" (pictured at left) to the Musée des Techniques du Conservatoire National des Arts et Métiers in Paris, but it was subsequently stolen. Fortunately, after three months of tinkering with the watch, the thief was apprehended when he took it to a renowned Parisian watch specialist for repair.
