Rolex watches are known around the world as a symbol of luxury and style. Rolex was founded in 1908 by Hans Wilsdorf of Germany. The company was initially named Wilsdorf & Davis (named for Wilsdorf and Alfred David, his partner and brother-in-law). At the time, Swiss watch manufacturers were mostly producing pocket watches because the science of producing accurate movements in miniature fittings (i.e. a wristwatch) had not been perfected. Wilsdorf was a perfectionist who improved the standards for watch making as he developed smaller, more accurate movements. These innovations eventually propelled the transition of style and fashion from bulky pocket watches to smaller, more practical timepieces that could be worn on the wrist. Rolex partnered with Aegler, a small Swiss company that supplied movements small enough to be worn on the wrist.
