Yep same here the one I have has 4 settings of a minute each up to 4 min's I just run it through twice so 8 min's total usually turning parts half way through and like 'dadistic' I also use a couple of small glass jars with cleaning solution in placed in the bath of normal tap water. Any plastic I've found clouds and degrades so don't put plastic parts in. Mine came with a free sample of SeaClean2 Ultrasonic cleaner which I have to say does a fine job but I also use lighter fuel but remember it is combustable and ultrasonic cleaners produce heat when cleaning.

For the moment I clean in VM&P (Varnish Makers and Painters) Naptha, and rinse in Anhydrous (no water) Isopropyl Alcohol, to remove any residue and provide fast drying. I dry the parts with a hair dryer so no water condenses on them. I plan to buy some real watch cleaning and rinsing solutions soon, just waiting for the budget to catch up to the wish list. :)

I also use naphta and alcohool. 

 

But imho this ultrasonic cleaning should be done as a final stage. The thick gummy oil and dirt should be addressed with a brush and pegwood (under naphta).

Hey. One more thing about the ultrasonic cleaner. You put the parts in the beaker with the cleaning fluid and then you put it into the cleaner (which is already filled with tap water) so the beaker floods with the tap water?

Or do you keep the level of tap water lower than the beaker edge?

Thanks.

I have used this type of cleaner for a long time now without problems.  I use the small jam jars like the ones you get in hotels and restaurants set into tap water with the lids back on. I bought some small wire ball cages for really small bits.  For general cleaning And first wash I use lighter fluid but only the sort that is pure Naptha as some fluids have other ingredients - the side of the can should advise.  My rinse is pure Isapropanol as this leaves next to no residues. Check your fluids by putting a few drops on a small mirror and allow them to evaporate. If there is a residue this will be left on the glass use a dark cloth to wipe it to see.

I should mention that I do not use professional kit as I only ever clean in small amounts being a tinkerer/ hobbyist rather than a pro.  Buying gallons of wash and rinse along with a full machine would be pointless for me.

Also this topic is well covered in the forum if you want to do a trace. Also well covered are the warnings about not ultrasonic cleaning pallet forks with jewels attached by shellac in solvent cleaners.

Cheers,

Vic

For cleaning watch parts I use Travena Safety Solvent Cleaner as a cleaner and final rinse, it's an organic cleaner. I also use it on electronic components. I leave items to dry naturally or somtimes blow dry. The manufacturers say it leaves no residue and I've found that to be the case. I've not experienced any problems, yet.

If anyone wants to try it, test it on scrap watches first to make sure you're happy with it.

Hi guys, i've been looking at purchasing an ultrasonic cleaner. Through searching the forums i have been lead to this thread so i thought id give it a bump instead of creating a new topic.

Since i made some big mistakes on buying expensive tools when i didn't really need to, i thought i'd ask what is the difference between these two cleaners? I can see the Elma has a heater but i don't need that as i can just use a hairdryer and also the frequency is different. The Elma is 37hz and the 7000s is 42hz, is there an ideal frequency? The one featured in this thread is similar to the James7000s. So the James is £20 and the Elma is £300 any need to spend the extra £££??

This is the same as the one I use, but without a heater.

If you watch repair is purely hobby, this is more than good enough.  I find the heater on mine not necessary as I just fill it with water at 50 degrees centigrade and place the components in small jars with cleaner in them.  When running, the ultrasonic transducer keeps the water warm enough for the job.  Remember to pre-heat the jars of cleaner before you start by placing them in a basin of warm watter first.

Thanks Geoff very interesting. I shall definitely save my money [emoji1303].

I was just wondering (this might sound stupid) but if you place your beaker of cleaning fluid with your parts inside the ultrasonic cleaner how do the waves create agitation inside the beaker/jar? Maybe I'm missing something here...

The ultrasonic vibrations penetrate the glass.  Using small jars is the most economical way of using cleaner.

I think the ultrasonic leaner I recommended comes complete with basket for playing your jars in.

I've cleaned things directly in the tank and indirectly in jars with no difference in cleaning quality whatsoever.  

For items like watch cases and bracelets, I just place them directly in the basket an use plain water.

And what type of cleaning fluid do you use?

I agree with Szbalogh. All of the printing is already lost so there is nothing to lose by refinishing.

The applied indices and logos all have tiny posts on the back of them which fit into holes in the dial. Carefully push them out from the back of the dial so as not to damage them or the dial. Then you can refinish the dial surface and reinstall the indices.

To be honest though this is a Constellation dial and as such it may be worth getting it professionally restored. As a redial it will never have the value of an unrestored original in good condition, but it will at least have the printing, which unless you are set up to do this properly, a DIY cleaning job will lack.

    • If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hairdrier) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem. 
    • How long had it been without any wind before you first put it on the timegrapher?  Perhaps there was some debris / old lubricant that loosened up while you were waiting to do the 24 hour reading? I recently serviced a Seiko 6319 that immediately after service was absolutely horrible on the timegrapher - 24 hours later (without me doing anything) it was rock solid!  I was a little surprised by this (as I have seen improvements in amplitude after letting it run in but never a watch going from useless to great!). I was suspicious that some dirt must still be in there so I took it apart and cleaned and lubcricated it again and had exactly the same experience - snow storm that after some hours turned into a nice straigh line with good amplitude 🤷‍♂️
    • Yes, I know it was able to run before just enough that everything supposed to be affixed with shellac could fall out. I won't get back to work on this watch for several days at least, but one thing you mentioned about the banking pin adjustments being intended for fork horn clearance got me wondering.... The last adjustment I made to the entry stone yesterday did not solve the problem when the balance is installed. The escape teeth can't quite clear the stone when the balance swings. But I thought it was going to work because manually snapping the fork back and forth did allow the escape wheel to advance almost all the time. I wonder if there's another issue with the impulse jewel, that I have to shellac again anyway. I am going to measure the fork slot and the jewel because I am curious if it is the right size or possibly narrower than it should be. My thinking is if the horn clearance is too great maybe it is not getting enough impulse to clear the escape tooth. But pushing the fork with a tool can move it far enough to clear the escape wheel tooth.  I'll see later in the week. I didn't expect a big challenge from this watch because it ticked for 5 minutes before stopping without shellac. As always I was way wrong.
    • I had one success (and one failure) dissolving a broken stem out of a crown with Alum. The successes was a stainless steel crown and a milder steel stem. A Tag Heuer 2000 Automatic - here with the solution at around 60ºC I could see small bubbles coming up from the stump of the stem and it took maybe 6 hours to disolve I tried to repeat this with another watch and it did nothing.....  This was A Bulova Ambassador with what again looked like a stainless steel crown.  
    • That good to know in one way.
