Rolex is a Swiss watchmaking company that was founded in 1905 and still makes the world's most sought-after wristwatches. There are several factors that go into the value of vintage Rolex watches. As with all watches, the condition of the watch is the primary consideration. Watches in like-new condition, and with their original wristband, are worth considerably more than those that are showing signs of wear. Certain vintage Rolex models have historical importance, or were considered the first of their kind for technical breakthroughs. These include the Oyster, the Datejust, the first watch to automatically change dates and the Submariner, the first watch designed for deep-sea divers.
