Does Rolex make its own movements?

Now that Rolex manufactures there own Hairsprings its safe to say the entire movement is in house. Yes, the movement although simple is proven to be accurate and built to last many lifetimes.

Agreed, and simple is the name of the game - for example, the new Daytona movement, the Rolex 4130, uses far fewer parts than comparable chrono movements.
