I have used this guy before. Very good indeed but a bit slow with delivery times to the UK. Always worth a visit to see what he has. £200 for an Elma is an absolute bargain if you are still having issues it is most defiantly not your equipment. It is the fluid or whats already on the watch contaminating the fluid.

There good I had an old one for cleaning clock screws in old cleaning fluid and rinse. I don’t think you will have any problems with that. Not a bad price and it looks in good condition.

I was looking at my bottle of cleaning fluid and I'm using 111 Ultrasonic Watch Cleaning Solution Ammoniated. I'll have to check at work I'm not sure which fluid were using. But it's interesting according to the material safety sheets it is a trade secret the actual quantity of the chemicals but both solutions are identical in chemical makeup just slightly differing quantities of each of the chemicals. then the cleaning fluid color is it correct? The original gallon that I purchased a very long time ago seem to lost its effectiveness so I purchased another gallon. Even that is at least five years old. So looking at the color of each the original is a very dark translucent yellow more perhaps of a orange color. The newer is a nice crystal clear yellow. then rotation speed Omega has a documentation probably just about everything but this one is on cleaning. For spinning speed in the cleaning solution there are two separate times depending upon whether you're using ultrasonic or not. So with ultrasonic 20 revolutions per minute without 200 to 300 revolutions per minute. I don't suppose you have any other watches to clean? Preferably a watch that's already clean or as an alternative find some clean metal to clean? The example of clean metal would be to find a modern coin made out of one of the nickel alloys although I'm not sure he could probably clean just about any metal coin pick one that shiny and clean and run it through the cleaning machine and see if it's shiny afterwords. Otherwise clean a clean watch.

I acquired an old ETA 2824 movement that was out of a Technos watch. While taking it apart for a thorough service I learned quite a bit about the movement. The keyless works, date change parts, sliding and winding pinions were different to the current ETA 2814-2. The stem was of the helicoidal type - but was missing. I was very lucky to source some. I also changed to rotor for a new Swiss one. I had great fun in stripping it down and, as this was my first ETA 2824 service, was amazed at the quality of the components. When I opened the barrel, the spring was almost mint condition, in fact, I think the movement had hardly been used. Now, after its service and bringing it back to life, I think it's a fantastic movement. Here are a couple photos and a video of the timegrapher readings. I think I could even improve the -/+ sec/day setting. Timegrapher readings for dial side up and crown down. There's not much fluctuation in other positions.
