Audemars Piguet is most often associated with hefty Royal Oaks, but what a lot of people might not know is that they used to produce one of the world's thinnest movements – the caliber 2003. Here you have an excellent dress watch retailed and signed by famed luxury Swiss retailer Gübelin that also houses the 1.64 mm thick movement. Not only does this watch look great – it also comes with its original box, invoice from Gübelin, the check that bought it (for $486), and extra mainspring. For more on this watch click here.
