I clean a lot of watches every week and rely on my trusty 'dishwasher' otherwise known as a Fuji 101 Automatic Ultrasonic Watch Cleaning Machine.
I have used this machine since the 70's and it has only ever had minor electrical connection faults in all this time.
It has two cleaning jars and three rinses with a dryer and takes around 25 minutes to complete the cleaning cycle.
The ultrasonic jar is powered by a thermionic valve and literally rattles the dirt off leaving components absolutely sparkling.
Made for a time when watches were hardly dustproof let alone waterproof it was designed to remove even the most stubborn dirt and dried in oil and grease.
This has proved most useful when cleaning today's watches where the components are often much smaller and have finer parts where oil and grease can be difficult to remove entirely.

Case in point is this Jaeger Lecoultre Reverso which was keeping a very poor rate because somehow dried in oil was present in one of the pallet pivot holes.
As we know, Swiss pallet pivots should not usually be oiled so that when they give impulse to the balance this impulse is not dampened in any way.
Here is the offending pivot hole. No idea how oil got there. It probably was because the pallets were not cleaned before assembly at the factory. It happens !

The watch was completely dismantled and placed in the cleaning baskets.
I seem to be having a problem attaching more than two photos via this app.
Sorry !
Have the rules changed ?
