The Freak openly displays everything. Every single part of the mechanical movement is visible. The two bridges indicate hours and minutes. Resetting is effected by turning the top bezel.

While the mainspring barrel rotates, the fixed rack transmits its power to the movement.
The hour wheel arbor is mounted on the blue mainspring barrel. The wheel rolls in the fixed rack and drives the centre-pinion. The grey bridge rotates once in 12 hours and is used as hour hand, too.

The Carrousel-Tourbillon movement is assembled onto the centre-pinion. Its first wheel rolls on the fixed rack and gathers the necessary power to maintain the oscillation of the balance.

How does this escapement work?

Step 1:

The BALANCE is about to move the STOPPER and to unlock the 1st WHEEL.

Step 2:

When the BALANCE passes its neutral position, the 1st WHEEL is freed and accelerates in order to catch up with the Balance IMPULSE TOOTH.

Step 3:

The 1st WHEEL gives an impulse onto the Balance IMPULSE TOOTH.

Step 4:

The BALANCE rides along its free arc, the 2nd WHEEL sits against the STOPPER.

Step 5:

The BALANCE returns to move the STOPPER and unlock the 2nd WHEEL.

Step 6:

The BALANCE passes its neutral position, the 2nd WHEEL is freed and accelerates in order to catch up with the Balance IMPULSE TOOTH.

Step 7:

The 2nd WHEEL gives an impulse onto the Balance IMPULSE TOOTH.

Step 8:

The BALANCE rides along its free arc, the 1st WHEEL sits against the STOPPER.

And this is how the whole process appears in motion:
