Audemars Piguet are one of the top selling watch brands, mainly due to the Royal Oak. However, there are plenty of other fantastic offerings in their vintage catalog through the decades, especially with regards to their dress watches. AP are known for some of their highly technical and complicated dress pieces as well but these can get wildly expensive and can frankly be difficult to operate and maintain. That brings the affordable AP category and their Ultra Slim or "cocktail watch." This example is 18k yellow gold and at 31mm is the perfect size for medium to smaller wrists. It has remained in fantastic vintage condition with a mint dial and unpolished case. This one even retains its correct 18k AP pin buckle and is ready to enjoy for years to come.
