The Skyracer is powered by a mechanical self-winding chronograph movement, Caliber 27.

This watch movement is capable of displaying dual measured times. The 60-minute counter (on the right) can display times under one hour. For times longer than one hour, a single two-hand counter (on the left) shows hours and minutes. The elapsed time can easily be read off this subdial, just like you normally read the time. Very cool.

The Breitling Skyracer Raven Special edition has a rack-and-pinion mounted slide rule and a 43.5 mm diameter case. The Skyracer is 200 meters water-resistant and retails for $5,710.
