The Jaquet Droz Charming Bird wristwatch is as far from the world of useful, utilitarian tool watches as it is possible for a watch to be. In fact, it’s barely a wristwatch at all – in architecture, you’d call something like this a “folly.” A building is called a folly when it’s either purely decorative, with a form that suggests a practical function, or when it’s simply extremely decorative. The thrill you get out of the Charming Bird watch, on the assumption that you find this sort of thing thrilling to begin with – whimsy leaves a lot of people cold – is the same you get out of watching an especially good magic trick. It’s a piece of mechanical sleight of hand that, unlike actual stage magic, is more fun the more you know about how it works.
