[填空题]
For more than a century and a half, Patek Philippe has been known as the finest watch in the world. The reason is very simple. It is made differently. It’s made using skills and techniques that others have lost or forgotten. It is made with attention to detail very few people would notice. It is made we have to admit, with a total disregard for time. If a particular Patek Philippe movement requires four years of continuous work to bring to absolute perfection, we will take four years. The result will be a watch that is unlikely any other. A watch that conveys quality from first glance and first touch. A watch with a distinction: Generation after generation it has been worn, loved and collected by those who are very difficult to please; those who will only accept the best. For the day that you take delivery of your Patek Philippe, you will have acquired the best. Your Pat& Philippe, you will have acquired the best. A watch that was made to be treasured.
