Elma Watch Cleaning Machine


Recommended Posts

Well, got most of it disassembled ready for the soak in acetone. One slight problem though, I can't seem to get the bottom casing off the base plate, the centre shaft won't come off. Mickey, can you advise how this comes off? I've removed the bolt from the bottom, I'm assuming it then pulls out? Mine is stuck solid if that's the case, even after half a can of WD40!

As you know I purchased a vintage Elma cleaning machine recently. Being the curious type and always looking for input as per Jonny 5 (Short Circuit), I sent an Email to Elma asking what year it was made.

To be honest, I didn't really expect to get an answer, as I have contacted companies in the past requesting this sort of information and have had no reply. Well not Elma, within a couple of hours their Technical Support Manager git back to me to say that it was made in 1966.

I thanked him for the fast response, and that it was greatly appreciated. The next thing I receive another email saying "To be honest this is a version I never have seen before. I collected some for our Elma museum...all are different." This got me thinking, has someone modified the machine sometime in the past. I responded by asking him the question.

Back came an immediate reply "I trust this is original design - one of several varities during the years.

Hans Schmidbauer, a Swiss watchmaker was the founder of Elma in 1948. now the Company is still in family hand 3th generation.

Good luck with the machine."

I wish more folk were as helpful!

That's awesome Geo...and to tell the truth you might even have a unique version of the machine...might even be worth an exchange for a new one if they have a museum! I know the story of a guy here that had an old chevy and was offered money and a new model by the factory...I don't know the details but it definitely is something to think about.

 

In any case, that's a professional quality machine that will give you service for years to come.

 

Cheers,

The strange thing about that is that it is now working. Didn't do anything either, it just decided to kick on?!!

To be honest, I generally keep it on the fastest speed anyway unless I have a particularly heavy item in the basket, then I will slow it down until the vibrations stop.

It's always good to get such a courteous response, isn't it? I bought a J.W. Benson watch a few months ago - cased by Louis Audemars of London - and a descendant of the firm sent me lots of fascinating information about the doings of the firm in London.

Looking good Paul, regards the motor, its speed, and functionality, its impossible to grasp the speed with the basket out of the chemicals.   Here's a couple of demo videos I just shot for you, the first one out of the chemicals, speed variances, and the second, the same speed changes whilst submerged, the motor feels the velocity of the liquid, and in turn you achieve the correct speeds.

 

Its also worth noting that the central shaft that goes through the motor should be completely cleaned, no surface rust should be present at all.  Using some fine sandpaper whilst the motor is running can clean this up, be careful not to catch yourself anywhere.

Thanks for that Micky, I've cleaned the shaft up, I got all the rust off with a grinding wheel, then polished it back up to give it the shine back. It's looking good. The motor seems ok now, speed wise. I guess I'll find out when I out it all back together and give it a test run. I'm just waiting for delivery of the acetone to strip the old paint.

    • It sounds as though you are happy with this situation and have no ill feelings towards Swiss manufacturers whatsoever.  😄
    • Hey everyone I enjoy tinkering and used to get my fix by making knives, but with a baby (now toddler) that hobby has been put on pause.  My co-workers dad used to be a watchmaker but had to stop due to arthritis. I was lucky enough for him to give me some basic supplies to get started along with some busted movements and books. After destroying one movement I signed up for Mark's online course and have made my way through half of it while working on a couple of my own movements. Eventually I'd like to get to the point where I can buy vintage pieces and restore a handful a year. There is surprisingly little information on watchmaking and this forum has already been a great help. Cheers! Adam  
    • Any chance you can take some pictures and give a quick review of the tool? I suspect many of us will be quite interested in this tool.   I agree that some of the Swiss-branded tools are at least made in part in China, but touched-up/finished marginally in Switzerland. On the other hand, some of the Chinese tools are really a direct clone of the tool, which wouldn’t be so vexing if they actually worked as advertised: I bought some pallet forks for 2824-2 from china which were advertised to be compatible with ETA 2824-2 but couldn’t fit in the jewels. I have had better experience with Chinese tools that have their their own branding (such as Weishi), but even then, there are sometimes multiple listings on AliExpress of seemingly identical items with different Chinese brands. I would think that if one was a Chinese-speaking watch enthusiast in China, it would be easier to locate reliable Chinese tool manufacturers (as @HectorLooi previously mentioned) but for us, we have to rely on actual reviews from people who own the item!
    • Wow a thousand pound watch and the stem removal is booby traped by poor design 😎
    • I have just taken delivery of one of these myself.  After the nightmare I had with a Tag Heuer where the seconds hand popped off its tube when I used hand leavers like I always did with all the other watches I have stripped down, one set of Tag hands cost me £120, so the price paid for the hand lift tool £145 is not so bad if it saves me from that nightmare situation again. They are well made and a quality product, just got to wait for the next Tag to land on my desk to try it out in anger. Also remember not all these Chinese tools are clones or copies, some of them are the same tools some of the Swiss makers claim to make, they have their tools made in China and just package them in made in Switzerland boxes. I have some that are so identical the parts are fully interchangable with the Swiss version and all the machining marks are identical, showing they are off the same production line, and just sent to a different logo printer. The Swiss watch industry is a very shady industry, from watch makers only being bracelet makers who use a generic movement from a movement maker to the likes of Rolex who although they are a multi million company don't pay any tax because they are set up as a charitable organisation but only fund themselves, to their tool makers who have their tools made in China but claim they are made in Switzerland and charge over inflated prices for the same tool that can sometimes be bought direct from China at a fraction of the price the Swiss charge.
