With his Zenith firmly attached to his wrist, Felix Baumgartner launched himself into the stratosphere from a space capsule suspended from a helium-filled balloon. He did so at an altitude of 39,045 meters – four times higher than airliners fly – and at a temperature of -62°C.
When he threw himself into the stratosphere, Felix Baumgartner reached a record speed of 1,342 km an hour, before being slowed down by the atmosphere during his freefall that lasted four minutes and 20 seconds.
He subsequently opened his parachute and landed safe and sound in the New Mexico desert. In all, the jump lasted nine minutes and three seconds, and set three new records: the first jump in history to break the speed of sound in freefall, the highest occupied flight in a balloon, and the highest freefall. The Zenith El Primero Stratos Flyback Striking 10th that accompanied the feat was still working perfectly upon arrival after being subjected to massive differences in pressure, temperature, altitude and acceleration.
