L & R Varamatic Watch Cleaning machine

Recommended Posts

Hello all;

  I am looking for some guidance on an L & R  Varamatic machine.  It seems to be  timed properly but  the basket goes onto the jar and immediately  comes right out and  does spin-off clear at the top of it's cycle rather then stopping in the top of the jar.    It would throw solution all over the place if you used it.     When I got it the  timing screws were  screwd all the way down in an effort to control the time it set in the jars but that didn't seem to work .   Any help or guidance would be gratefully accepted.

I have that exact machine sitting in my garage waiting to be repaired. It ran out of hydraulic oil and the timing went belly up. Just have not had the time to fix. In the mean time I purchased the cheapest Chinese machine named a Pearl (see below) Mine has no timer but considering the price it works incredibly well.

Hi, firstly, it's worth mentioning that these are absolutely fantastic machines and well worth renovating. It takes a while to get your head around their operation, but this is simpler when the two halves of the casing have been removed to allow you to observe the workings.

One of the most common faults is synchronisation, which is when the main cam which sits underneath the turntable which holds the jars moves such that it is rotated slightly compared to the turntable position. However, it does not sound like you have this fault. The obvious symptom with this fault is that the turntable tries to move when the basket is either in the low position, or rising/lowering.

You describe the basket as spending literally no time in each jar, despite the time duration knobs being set to maximum. This makes me wonder if the "timer assembly" unit has failed. Can you have a look at it? It's an odd device which is a simple switch which has a lever that's motorised which very closes very slowly. The knurled screws which adjust the timing length push the lever on the timer assembly open by varying amounts, and the further they are screwed in, the longer it takes the timer unit to close the switch.

Hi clockboy, where did you get your Pearl from?

I will watch this closely as im considering a Varimatic?!?

I picked my one up on eBay. There is another copy of this machine named a "Janta" 

Both of theses machines are just a  copy of the Elama machine. The biggest difference between the Vari-matic and these machines the baskets just spin in one direction, the Vari Matic baskets revolve in both directions when washing.

I can't find them on Ebay anywhere, only on Alibaba. According to the manufacturers website they do one with a reversible motor now.

Thanks Rodabud I have come to the same solution.  This is a second machine that I had planed on repairing and then selling but If I cant I will keep it for parts. and I still have both  bottom units to sort out.

A nice thing about these machines is the ultrasonic is variable in intensity from zero to full force; when dealing with really old pieces it can be nice to dial it back as the old natural jewels don't necessarily like full blast ultrasonic.

Looking at the timer, the trigger bar only moves about 1/32  and it seeps to be way too low to contact anything.  The illustration in the manuel show it sticking almost straight up. That makes sense in that position it would easily make contact with the timing screws.   Does this make sense?

That makes sense.. So, each screw should knock the arm on the mechanical timer by a number of mm. You should be able to exercise the arm to see how it operates. If you have a multimeter then you will also be able to see how the switch terminals on the side open and close depending on the position of the arm.

I recommend powering the unit with an RCD at all time, especially when the case is open!

I  removed the timer assembly and found that the trigger bar had been pushed back. I spun it back around so that it would make contact and in the process a wire let go  poor solder joint.     I have two ultrasonic base units I would like to send to someone and get them repaired.  Is there anyone around that  troubleshoots/ repairs them?

    • Today I found out the MOERIS is a perfect counterweight on the arm when removing the balance from a dodgy AS970 balance staff. It is a UNITAS 6498 Pocket watch conversersion which will give you the perfect swagg when walking the stripp .
    • Wish I saw this post ten minutes ago, yep you guessed it, I’ve got a damaged main hand now, oh well live and learn as they say
    • Just to avoid making too many new topics with the same subject I will post these PDF:s in this old thread. Since flashplayer is obselete due to security lacks and not every one wants to activate it I have made some PDF:s with two of the most popular movements. This version uses a normal PDF format which you can print out and make notes in while servicing the movement, you can brows them offline while lapping sun. ETA 7750 Chronograph. ETA 7750 Service Notes.pdf  ETA 6497  SwissLab_6497 Service Notes.pdf
    • Thanks for the input Marc. The Bulova was the one that had me interested. As you sa,y at $4.75 each it would perhaps have been worth a gamble -  even to break and flip the unwanted ones to pay for the keepers.  
    • Here’s some shots of the movement, it’s all back together at the moment and running strong, only lost 3 mins in 12 hours so I’m happy with that, even with that canon pinion, which I shall find a replacement for. I had another post a while back asking for information on the “ climax trip action” a few that answered said it was to do with the case but I’m not sure.  If you look at the top plate there is a wheel mounted on a yoke by two screws, one screw is fixed the other allows the yoke to move by a few mm via an elongated screw hole. you will notice a silver spring bar screwed to the plate which in turn locates under the wheel in a groove, of which there are two, not dissimilar to a setting lever. Now all I can see is that the wheel provides an interface for the barrel and then to pass the power to the train, I have no idea why it should be allowed to move or why, I can only assume that this piece of the movement is the “climax trip action” as I have never seen it on another movement.
