The rolex diamond bezel often serves two very distinct purposes. In many cases, it has a very specific technical function. The rotating bezel on the Submariner makes it easier for divers to keep track of the time they have spent at certain depths and how long they have been under water altogether. The Daytona's bezel doubles as a tachometer and the 24-hour graduated bezel of the Explorer II allows a climber to more easily monitor the length of his journey up the face of a mountain. The bezel is not always related to serving a technical function, though. Often, it is the most spectacular looking piece of a watch. In fact, many Rolex watch bezels are so ornate and bejeweled that they alone cost far more than most watches on the market.
There are a number of different diamond bezels available for different Rolex watches. The diamonds on these pieces are set in 18k gold. Larger diamonds can also be found in the same style bezel. The larger cuts will often cost more. There are bezels styles available for both men and women. However, there are a number of choices that are designed solely for women's watches. It is also possible to find channel set diamond bezels. These pieces can draw attention from across the room, as the series of diamonds on an 18k gold base causes the entire watch to sparkle. This design is often offset with a gold and diamond watch bracelet, which can tie the bezel into the rest of the watch design.
