Patek Philippe, owned by the Stern family, is one of the most famous brands of wrist watches worldwide. Among its customers include celebrities, movie stars, wealthy businessmen, and even members of royalty. It first began when Antoni Patek began producing pocket watches in 1839 in Geneva. At first, Antoni Patek united with Franciszek Czapek, and together they managed the business. In 1844, they split up and Patek merged with Adrien Phillipe the following year. Soon enough, in 1851, the Patek Philippe & Co. began. The first wristwatch was created in 1868, and was followed by many different types of watches, including watches that displayed the perpetual calendar, the minute repeater, and chronographs. The infamous Calibre 89, created by Antoni Patek, has been regarded as the most complex mechanical watch ever to be created. This watch was made in 1989 to commemorate the company’s 150th anniversary, and it truly defines 150 years of excellent watchmaking. It has numerous indicators, including indicators that display the date of Easter, the time of the sunrise, a thermometer, the sidereal time, and many others. Patek Philippe also created the world’s first wristwatch that includes a power reserve of up to 10 days, an amazing invention. Among the current collection are the complicated watches, which included the grand complications, men’s complicated watches, and ladies’ complicated watches. The classic watches include Calatrava, Gondolo, and Golden Ellipse models. The casually elegant watches include Aquanaut and Nautilus. And finally, there are the jeweled watches. Patek Philippe, known as one of the most prominent watchmaking companies in the world, has earned the prestigious Geneva Seal, which is stamped on all Patek Philippe products.
