At first, Rolex didn’t make watches, they merely assembled them. The company purchased movements from Hermann Aegler’s Swiss movements and then put the movement into cases which were made by Dennison as well as other manufacturers.
At this point the name Rolex didn’t even exist, and the company made watches for jewelers. These watches weren’t branded on the dial, this allowed the jewelers to put their own names on the dial. The watches were marked on the inside of the casebook, with ”W&D”.
Today Rolex watches are handmade in-house with a crown on every dial. Rolex watches are meticulously, carefully crafted and put together to make sure they meet the high standards that Rolex is known for. Each Rolex taking an entire year to completely manufacture.
