Take a look at the Perpetual rotor self-winding mechanism, which is one of the 400 innovations patented by Rolex in the last 90 years. When Rolex watches have solid case backs, it is nice to see this:
Below is the Rolex silicon hairspring in action:
I also love the animation of the vertical clutch of the Daytona. It works on the principle of friction contact between two discs, like the clutch in a car:
Below is the Triplock winding crown of a GMT-Master II, which has three sealed zones fitted with high-performance gaskets:
Another Rolex invention is the gas escape valve for the Sea-Dweller. It allows the helium trapped in the watch to be released at a given pressure during decompression. It is a one-way safety valve:
