I live-streamed during the release that night....waited till 2pm++ just to see that watch. Whopping 3.6million beats per hour if not mistaken
I think the chronograph balance wheel should oscillate at 360,000 bph only.
1/100 second chronograph translates to 100 beats per second.
In 1 hour that comes up to 100 beats per second x 3600 seconds = 360,000 beats per hour.
Please correct me if I'm mistaken. 
The mikrotimer 1/100's chrono balance wheel oscillates at 360,000 vph = 100 vibrations per second.
The mikrograph flying 1000's chrono balance wheel oscillates at 3.6 million vph = 1000 vibrations per second.
This is the official Tag video... pretty cool.

Central 1/1000th chronograph second
Chronograph minute and 1/12th of minute on central hand
Chronograph 1/10th of a second at 6 o’clock calibrated to 5 seconds
MECHANICAL FEATURES
1/1000th second chronograph function
High frequency mechanical regulating 500hz spiral for chronograph (patent pending)
(gives static stability and extremely high dynamism with limited dilation. Reduces gravity effects and shocks. Low amplitude increases the isochronous precision of the pulse)
Traditionnal balance wheel for watch
Automatic bi-directionnal rewinding movement
Stop second (when setting the hour)
