Well, I have to warn you from the very beginning: you are facing a very challenging box. To get access to the Logbook, all your senses will be tested at maximum. And more than this, two different elements will need to be 'handled' together to open the Box.
No special tools required. No excessive power needed. You may use a napkin to dry your sweat, but please, don't curse! You been warned about this box!
Rotating gears? Yes!
Magnets? Yep ... but not necessarily...
Hitting require? Never!
Switches? Hmmm ...
Balls inside? Just use your senses (see - hear - smell - smile)
Pulleys? I already released too many hints...
Unlocking Code? Are you joking? :-)))
Magnetic Compass needed? As an indication only, it help but not needed.
Hmmm
Please ensure that once you sign the Log you will lock the Box the same way you found it and kindly ensure that no elements of the solution are disclosed to the next Geocachers. Don't spoil their attempt, so they will enjoy the same experience!
