If you are considering purchasing a Patek Philippe watch, it is wise, first, to understand all the options that are available and then to scrutinize them. Choosing a Patek Philippe watch includes considerations of size, dial material (most notably, mother-of-pearl), type of movement, and diamonds or other precious stones. These factors determine the price range. The main consideration is what you plan on using the watch for to decide which is most important to you. Your watch collection should not just consist of Patek Philippe watches. Other luxury watches are of the same caliber in terms of quality and craftsmanship. A good example is Audemars Piguet Royal Oak Offshore Watches. Audemars Piguet is available in three collections: Millenary, Royal Oak, and Offshore. In terms of functionality, they all have the same features with only minor differences such as size and water resistance. They all offer automatic movements with an additional hand showing the date. Other luxury watches to consider include Cartier, Vacheron Constantin, Panerai, IWC, Jaeger Le-Coultre, and Rolex. Each watch has its uniqueness which makes it worthwhile. You may want to consider a watch in a different collection than what is considered normal wear. This allows you to express yourself in your choice of watch. You can carry two or three Patek Philippe watches if you have a variety of designs and colors together.
