That is friggen nuts. I am always amazed at the ingenuity of humans. Electrical engineers needed to be involved somehow:)

Bingo , you are correct ,...engineers were involved .  Simply speaking , [ so even I can understand it ] , like a magnet , electro magnet to be more precise , a current is induced to attract the balance with the coil to some magnets in the base plate , the circuit is interrupted , then the hairspring  causes the balance to return in the opposite direction , a current is induced to attract the balance in the other direction , once again the circuit is interrupted and the cycle starts over .

If I didn't explain the exact operation , I'm pretty darned close . :jig:

So I'm an electrical engineer and completely understand your explanation. The big question is how does one clean one of these babies and is any of the mechanical watch cleaning solution relevant

Taking Geo's good advice , I have started a new thread....Cleaning an electric watch .

  • 1 month later...

I've always cleaned parts by hand, but now looking for specific experience of cleaning fluids, having just acquired an ultrasonic bath.  I don't get time to work on more than 1 watch a month at the most.  For hand cleaning I've been using renata essence, but since it's flammable and evaporates quickly I didn't  think putting a jar of it in an ultrasonic bath would be such a great idea... however, it appears that the bespoke ultrasonic fluids are also listed as flammable, but not quite so bad.

Cousins sells 4 main brands - Bergeon, Elma, Greiner and L&F.  I'm leaning towards the Elma WF Pro cleaner and Elma suprol rinse  which can be had in 2.5 l containers, are water free, ready to use but would appreciate opinions before I spend my money. I note that the cleaner contains ammonia so whilst it will brighten metals which tarnish, it is important to limit exposure.

Thanks

If you are using a ultrasonic bath rather than a  multi jar cleaning machine could you not use water in the bath but then place your parts in a separate container with the chosen cleaning fluid in it and put the full thing in the bath, then you could use a simular container for a rinsing fluid and just transfer the parts.

Containers you put your fluids in could even have a lid on to keep the fumes under control. You can also only use a smaller amount of fluid, rather than filling the full ultrasonic with fluid.

That's exactly what I do. My ultrasonic cleaning machine is large as I use it more for weapons cleaning. When I'm cleaning a watch, I fill two small Pyrex glass cups with solution. One rinse and one clean. I put the parts in Bergeon baskets and place them in the Pyrex. Works like a champ

Thanks for the info, I too was mainly using the eccense of renata for hand cleaning and some off the shelf ultra sonic cleaning solution,  I was looking at the L&r stuff at cousins but was undecided at what one to get, ill use isopropyl alcohol as a rinse agent as it's basically the same as an expensive bottle of branded rinse agent.

Now ive got to stump up the £8.50 extra postage from cousins due to it being a hazardous material!!!!!

Thanks everyone. Summary of above sounds like any of the main brands would be fine and zero votes for delivery by post.
I think L&R probably gets it. I had collected some jam jars to put in the ultrasonic before it arrived, but will need some smaller ones.

I use these for small parts like Accutron index-wheels in the ultrasonic--

The advantage is--being a sorta softish plastic, parts bouncing round due to the ultra dont get damaged as could be possible using a glass bottle/vial/beaker, being semi sealed you can use any cleaning fluid you like in them with just water in the ultrasonic tank keeping cleaner fluids costs down
--Yup. I'm a cheapskate!

Very useful... I have one of those in my queue for this year. I know the plastic attenuates the ultrasonic waves, but I guess you have found they still clean like this. What cleaning fluid do you use?

Thanks for the good idea... but even better if they had lids like jam jars, which was part of my plan.

Jut to piggy back off of this discussion, I am using an ultrasonic cleaner as described in the discussion above. I put soapy water in the machine. Into that I place mason jars that have my cleaning and rinsing solutions. I put my parts into those little parts baskets and place them in the mason jars. This seems to work well for the parts. 

Given that the mainspring is a larger and more unwieldy item, do you just stick it into the jar by itself, since it won't fit into the baskets? Is there a better way to clean it so that it doesn't get damaged?

Well I can now highly reccomend the L&R ultra fine cleaning solution, mine arrived today and I used it on an old waltham pocket watch movement. WOW, its the best cleaning solution ive used, every part nice and clean and also shiney, followed by two rinses and a low powered hair dryer .

I'm seriously impressed and will be looking forward to now saving time and getting great results in my next job on the bench.

Are you using this with a mechanical or an ultrasonic cleaner?

Ultra sonic, but I do like to hand clean aswell, now this is where you tell me I didn't read the small print and the ultra fine fluid cannot be used in an ultra sonic machine now isn't it.

must say I don't think it makes a difference as to how it's used, it does the job, I use it in a separate jar by itself in the ultra sonic machine.

    • I voted leave too, my reasoning was the the EU is undemocratic, no elected officials. I don't regret it but I  am sad that both sides acted like petulant toddlers.  Shameful.  I'm not on other forums but if I was and left this site, would you shun me? Of course not, we aren't petulant toddlers.  
    • This is a type of tool that may be suitable to remove the bezel - though note that I'm pretty sure the watch should be face down - not face up, as in some of the photos of these tools on amazon & ebay! If you try one one of those, put the movement screws back in first to avoid accidents. https://www.amazon.co.uk/Removal-Professional-Remover-Watchmaker-Diameter/dp/B09XCH4QVN?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&smid=A296NCMMFVXSDN&th=1  
    • Hi, I’m constantly asking my wife to help me with removing the stem in order to complete casing. To expand, this is not a challenge for me when the setting lever is secured by a screw (older calibers). However when the setting lever is attached to a spring loaded setting lever axel, like on more modern calibers, I simply don’t see how to apply enough pressure on the button to get the stem out short of putting the movement face down with the dial and hands attached, which I’m loath to do in order to avoid damaging the dial/hands? what technique should I be using? thanks  
    • Many thanks for your advice (being borne in mind at present) & offer Dell. When I was given the clock the plastic anchor was loose on the arbour (it had split at the 'hole') &, after repairing this, I have been trying to determine whether the spindle (pin) should be perpendicular when the pallet is sitting on a flat surface; or whether, when installed, its L-R extremes (or alternatively its tick & tock points) should lie at equal angles from the vertical when moved with spring absent. I can get the clock to run but in every such configuration the top block has to be turned anti-clockwise (from above) by quite a bit in order to be 'in beat' & it always runs fast (despite the pendulum being set to as slow as possible). This makes me wonder if there is any particular feature of/fault in a torsion spring clock which determines which turn direction (if any) is necessary to get it 'in beat'; & whether there would be a different set of settings that would get it running nearer to time at somewhere around the mid timing/inertia position which would then allow tweaking of the fast/slow setting.
    • Now this has happened I bet China or India just to name two will start to produce none genuine parts.  I did. But idiot Boris Johnson failed miserably in his negotiations. The E U stitched up the UK like a kipper. Nigel Farage  offered his help but big head Boris declined. So this is why we are in this mess all because Johnson wasn't clever enough.
