As per the title.

I wear my watches on a monthly rotation, and when I take them off at the end of their month, put them into my £30 Amazon cleaner for two minutes. Then of course dry them.

So, is the ultrasonics likely to be doing any harm to my watches?

 

If your collection consists of Invictas there should be no problem.

 

Given that they clean by vibrating enough to create cavitation in the water/solution, I'd say that's a bad idea.

 

Note that the previous post was a joke.

What watches do you wear on monthly rotation?

And some advice.

Stop what you are doing until we know what your watches are.

 

My previous post that is, not the Cookie Monster's.

 

Should be fine if you are removing the movement and dial first......

 

Other things not suitable for cleaning your watch:

 

Always wanted to ask @Archer

When doing bracelets do you put anything between the wire basket and the bracelet to stop scratching. ( have not used one yet due to not knowing )

PS it's a good one in the lab at work not a $20 one..

 

Here I've been using Miley Cyrus for removing small scratches in the crystal for years - and now you tell me it's not suitable?!?

What du you recommend then? Quick wash and tumbledry?

 

A microwave works so much better. Nukes the dirt and grime so it wipes right off - quick and easy.

And yes, works on cats too.

Sorry but I am still stuck on the concept of wearing the same watch for a month

 

Ok, so I may have lied about the month bit. It's a week at most. But, the ultrasonic bit is sort of every 4th ish rotation.
It does get any goo on the case and bracelet.

 

Before using the ultrasonic, may I suggest using something like this to get the really stubborn gunk off. But remember always start with course grit and work your way down to fine.

 

The only timepiece I clean in my ultrasonic without first taking it apart.

 

That's what you use Miley Cyrus for?!!?

 

The huge foam finger is required safety equipment when handling watches...

 

An ultrasonic cleaner is actually quite violent. I wouldn't insert a whole mechanism such as watch movement without first dismantling it in parts. That still applies in the case if the whole watch is dipped in the cleaner and no liquid reaches the mechanism (as you seem to suggest).
