I was hoping someone could give me some advice.  I’m an extreme novice at watch repair. By watch repair I mean I can break down a movement, clean it in my machine(old style L&R with the three jars), lubricate and re-assemble it. Issue I’m having is when I attempt to regulate it on my Timegrapher. I can get the beat error within an acceptable range, but when I attempt to adjust the timing it throws the beat error out of adjustment.  If I get the watch to within an acceptable seconds per day in the dial down position, it is thrown way off as soon as I change positions. I check all parts for any damage before reassembling. I check the hairspring to make sure it’s not getting hung up anywhere. I just have no idea what I’m missing. Any help would be greatly appreciated. 
Thanks!

First and foremost. The movement you are using, was it working fine before ? Are you sure that you're using a perfectly "healthy" movement ? It's important to know this... If there's some damage or problems in there, it might never really show the correct numbers on the tiemgrapher.

Do you have a specific watch in other words could we have the model number of the watch that's having a problem? Then a picture of the watch so we can see the layout of the regulator components. Otherwise generic questions get generic answers which may or may not apply to the specific problem watch.

So a generic answer with me having to guess the type of watch you have. So for that I've attached images I'm assuming if the wording you have a watch that the stud can be moved and the regulator can be moved? So to make sure you're moving the correct ones I've attached images. Sometimes there is confusion over which one does what that leads to confusing results.

So the problem of the regulating system like this is it has lots of range to it it's a very very sensitive to movement. Then the parts are stacked on top of each other they can move together even though they're not supposed to. This just requires lots of patients moving things around.

Then without specifics again too many answers to many questions. Just because you have a nifty timegrapher Capable of measuring depending on which one a fraction of a second doesn't mean you can regulate the watch to keep zero timekeeping in all positions.

So now that we have the background out of the way were still back to the specific watch. As a newbie you can stare at a watch all day and night and very likely you cannot or will not see the problem because you don't have the experience to know what it is you're looking for. As you've already stated everything looks perfect yet your perceiving you're having a problem. This is where we need a specific watch to address the problems one of the time. Then timing machine results it be nice if we could see those.

Props to you for wanting great precision, but if the watch is not designed for this kind of precision to begin with, you'll be trying to achieve the impossible. For a bit more perspective, to be "chronometer-certified", the daily variation must be less than -4/+6 sec/day (corresponds to a 99.99% degree of accuracy...

If every watch I take care of is within -10/+10 seconds per day, it's a win in my book...

It functioned properly and seemed to keep time. The only issue I had was the stem was a little stiff. It became worse, to the point where I tried to set it, and the crown would unscrew. The movement was pretty filthy so I thought a cleaning and oil would fix the issue. When I reassembled it everything seemed to work fine other than timing problem. It’s a Lorsa movement, which although I’m no expert, does not seem to be of the highest quality.

I'm a beginner as well and sometimes something like this happens and in most cases it was just the balance wheel needed a more thorough cleaning and then the reading was much better. In your case maybe dirt got stuck inbetween the regulating arms, make sure the hairspring didn't get damaged when timing it.

I’ve seen some watches where the regulator and stud both were designed to move and they were mounted sandwiched on each other. When necessary, I use a fine oiler and place a little oil around the area where the two components rotate on themselves. This helps to prevent one piece being adjusted but inadvertently causing the other to be moved.

    • I'd leave the Benrus till you've got more experience as information and parts are non existent and donor movements are expensive. I know it's based on something like an ETA 2370 but what they changed and what's still compatible is unknown.
    • Hello and welcome to the WRT forum.
    • No, a light. PS, it's a Unicorn   hehe. 
    • As a fellow newbie who's made a bunch of mistakes over the past year or 2 I'd like to offer my experience. I didn't start with a new practice movement, I started with 1970s Tissot that I loved. If I could do it over I would still use a vintage watch for my first movement. I wouldn't, however, chose one I cared about or that was expensive. It also had a calendar complication- dont do that. I learned a lot about part compatibility and movement families right away though! Emmy watch and Ranfft are great resources for this! I would start with the Benrus and go ahead and find a parts movement right away YOU WILL BREAK AND LOSE PARTS! Get good tweezers, it's much harder to handle tiny springs than YouTube would suggest. And be extra carful, pivots don't like to be forced into jewels - bridges are a real pain in the ass at the start. Don't be afraid to use your bare hands to hold parts/bridges and handle the movement. Finger cotts can come later. Be as carful as possible with hairsprings, this can ruin all the fun!  Buy a cheap demagnitizer. For me, I think its fine to buy cheap tools in the beginning and replace as you go. But some things I wish I'd have spent more money on right of the bat - TWEEZERS and Rodico (don't get the fake stuff). There's a great thread here on Chinese tools. I used a cheap digital microscope for a long time. I got quite good at working under it even with no depth perception. It's probably better to just use loupes but I think it helped me be more mindful and it was great for inspection. I now have a stereo microscope and if you get really into this hobby, it's a must. I cleaned everything by hand in the beginning. This is great for getting familiar with each part and learning to inspect for faults. Peg your jewels! I still hand clean a lot of parts before the ultrasonic. I still use JUST Naptha and IPA and I think thats adequate for my hobby purposes but maybe I'll have moved up in another year. I swish the shellaced parts in IPA for a few seconds to rinse (don't tell anyone). I used to dry each part on a sheet of paper with a puffer. Again, this is good for getting to know each part. I now dry everything in a food dehydrator. Im not going to give any advice on oil because thats suicide. But... until very recently I used just mobius 8000 and Molycote DX for everything. I dont know if I would do it differently If I were to go back but its definitely cheap and it will teach you how to apply oil.  Take a picture after every move even if it's just scratching yourself.  Wind mainsprings by hand until you decide you like the hobby, spend that winder money on tweezers and parts movements. This place is great, there are a bunch of incredible KNOWLEDGEABLE guys willing to help you. Unfortunately, this is as much as I can help, as I'm nowhere near their level.  Oh... and buy a big magnet. Still one of my favorite watches and it reminds me of all the broken pivots and pinged springs every time I put it on.   worth every penny.
