  1. Your dentist should be quite used to that. Many of our premium dental equipment from a certain country in Europe that produces watches, have learnt to impose ridiculous conditions in their warranties. If you don't follow their maintenance protocol, if you use a competitor's product in their machine, they retain their rights to void their warranty. Now with the Covid-19 panic, many companies are putting out infection control equipment that have not been tested and proven effective. I just bought one such equipment due to industry and peer pressure. If you follow the company's maintenance protocol, the cost of the spare parts for just 1 year would come to the price of a new machine. Ridiculous!
  2. I have a quartz clock which I bought more than 40 years ago. It cost me more than a weeks pocket money in those days. It's still running. It's still accurate to maybe 30 seconds a month. The newer clocks I have lasts about the life of 1 battery. And I just timed 1 yesterday. It was slow by 17 seconds per day. My 70 year old pendulum clock keeps better time than that. Over our lifetime, things have changed from "Made to last" to "Not made to last" and now we are in the era of "Made not to last." One of my friends who works for a mobile phone company said, "We are doing this for your own good. Or else we'll be surrounded with antiques. You wouldn't want to be using a Motorola brick would you?"
  3. Hey! Your 3rd video has been removed too! What was the original condition of this movement? I had a Seiko recently that had a similar problem. The guys here at WRT think it might have been a Mumbai special. It had a whole bunch of teeth missing but the 2nd wheel was in perfect condition. Most probably caused by improper technique when opening the mainspring barrel.
  4. WHOA! No oil on the commutator! Oil would mix with the carbon dust as the brushes wear down and form a sludge which would short out the commutator eventually.
  5. I salute your gallant attempt. I think your best bet is to take the motor to a motor repair or appliance repair shop to get it fixed. The two carbon brushes should have be removed first before taking the motor cover off. The 2 black bakelite knobs on the sides have screwed on covers. Unscrewing it will release the spring which pushes the carbon brushes against the motor commutator. It should be a simple fix for someone with the right knowledge.
  6. I lost a pallet jewel once. It was there on my work mat one moment then gone the next moment. I used a torch and searched high and low. I was on all fours for almost half an hour before I gave up. I said a silent prayer and when I was stretching out my aching back, I caught a glint on the floor just outside of my search area. It really was the missing pallet jewel. So my advice is when you are already on your hands and knees, it doesn't hurt to pray.
  7. It has happened to me a couple of times. I've become very paranoid when opening an Incabloc. I would always use a pegwood to prevent the spring from jumping out of the slot. When trying to put it back, rodico and fine tweezers just doesn't work for me. The grip of a fine tweezer is not strong enough to persuade the spring to get back into the slot. What worked for me was an eyebrow tweezer. The tips are wide enough to grip both arms of the Incabloc spring to give enough rotational force to get one end into the hole of the slot first, slide it all the way towards that hole then rotate the other end of the spring into the other hole. The reason why the spring comes out of the slot is because there is too much freeplay ( like endshake ), if the spring moves all the way to one side, the other end comes out of the hole and just falls out. But it's a bad day when an Incabloc spring falls out. It's not easy getting it back in.
  8. If you are in the US, buying Amscope is probably a good idea. At least they provide the first layer of QC. I also bought mine from a local microscope shop which charged me almost double of what was available from Aliexpress, but the local reseller could provide QC, one year warranty and advise you on what you'll need. But my microscope was fine for the first year, then almost just after the warranty period, it suddenly stopped being able to focus. I took it apart and found that the mechanism is incredibly simple. The optics are modular and if you do not fiddle with the lens components, it shouldn't be too difficult for a watchmaker to fix. My LED ringlight died last week, but it was only cold solder problem.
  9. These are zoom microscopes. The magnification is controlled by a separate knob from the focusing knob. The one I posted in the link has a trinocular attachment, so you can attach a still camera or video camera to it. It will make a very good teaching tool. There is a very steep learning curve for working with a microscope. But persist at it, it can be done. In dentistry, an operating microscope is being used for even routine procedures. Not just complicated root canal work and micro surgery. When I attended my first dental microscopy course, I couldn't even get a clear image in both eyes at the same time. I ended up with a severe headache.
  10. If I didn't have a microscope already, this is what I would get. https://a.aliexpress.com/_Bf9BlrRT Get a 10X eyepiece, a 0.7X - 4.5X zoom objective lens. If you want to increase the working length, get a 0.33X or 0.5X auxillary lens. You'll sacrifice some magnification for for the increase in working length. But it'll be more than enough for watch repair work.
  11. Thank you very much for all your answers. But resistance was futile. I went back to using Pledge because I still have a large can of it. I bought the can while restoring an antique longcase clock. The owner must have used Pledge in the past. Whatever I used, furniture polish, furniture wax, etc, just wouldn't work. It may look good right after I polished the wood but a few days later the white, moldy appearance returns. I found that Pledge was the only product that that could give a lasting shine. It appears that once an item has been Pledged, nothing else can fix it. So.... NEVER apply Pledge to wood if it has never been Pledged before.
  12. I just found this video on YouTube today. I wished I had watched this when I was starting out on microscopy work. It would have save me a lot of pain. I urge everyone using a microscope to watch it.
  13. Is it just me or does anyone else have a problem with Lemon Pledge? Lemon Pledge seemed like a godsend. You could bring back the shine to dull furniture with just a quick wipe down. My last cleaning lady got her hands on a can of it and literally Lemon Pledged every wooden thing in my house. But when you stop using it after a few years, the wood looks worse than it first started. I've tried cleaning it with detergent, Old English Oil, other brands of wood polish, even wd40. But the white, dried out look reappears after a short while. The only thing that restores the shine for a few more year is Lemon Pledge again. It was the same with Armor All. I hate to be forced to continue using a product for the rest of my life.
  14. I was watching your video again. The motor seems a bit slow. Do you have any way to measure the rpm?
  15. I've never heard of a pulsynetic clock before this. I watched a few YouTube videos to find out more. Oh noooo.... I think I'm hooked!
