ultrasound cleaning is used in the watch industry to clean watch case and bracelet especially after polishing to remove polishing wax that otherwise cannot be removed. those good things we read are true but they fail to mention that it is NOT a complete watch that they put in. rather, it is the midpart or casing without movement.
the freqency used for ultrasound is usually 25-45hz which is too harsh for delicate watch movement. i has seen pallet jewel come loose, hairspring foul, jewels dislodged from bridges and main-plate. endshake are also affected during such cleaning as friction-fitted jewels shift during cleaning. our robust rolex is design to handle shocks but not high frequency vibration over any period of time.
the video above does show a clever way of cleaning which does not immerse the head in the fluid so it is not affect by the ultrasonic vibration.
