      Hi all
      Does anyone know of a video showing the adjustment of a Rolex using the latest micro stella tool?

      Hello All,
      I'm wondering what tool is commonly used to manipulate the regulator arm? I've used everything from tweezers to a plastic stick used to help open up computers. My main issue is that all of the things I've used are risky for slippage and I find it incredibly hard to just nudge a little when you're really trying to dial in the timing. I would think there would be a special tool for this (there's a special tool for EVERYTHING), but I haven't managed to find such a tool if it exists. Today I made my own tool using an old broken spring bar tool that I reshaped that should make life a little easier, but I'm very curious to see what everyone else is using.
      thank you

      I am very nearsighted (between -6 and -7 in both eyes). With astigmatism. Now, in my late 50's I also have significant nearsightedness.
      I thought a flip up visor - which I could wear with my glasses would be best. I purchased an OptiVisor with a flip-down loupe. But not happy at all with the visual quality.
      I know you get what you pay for in optics. What is the best type of device for someone with old-bad eyes.
      I have never used a regular loupe - but thinking that may be the way to go. Any of you guys (or gals) have a reccomendation?

      If this is inappropriate, please delete the post.
      I have an acquaintance who is closing his shop due to health after 43 years.  He has a large quantity of parts, stems, crowns, crystals and all the paraphernalia one would accumulate after a long period in the business.  He needs to liquidate his shop.  This isn't a "Hey do you have a __ for a __." kind of post.  We're talking serious stuff here.  Mass quantities.   If you need parts, equipment, etc. for your practice, please let me know.  I will pass along his email contact  to you.  Obviously, this is useful primarily only to those in the U.S. due to shipping costs.  But he has a huge amount of useful goods and is 100 miles South of Atlanta.  PM me if you need something.

    • Hi Luiz  HSL is correct the inner ring  is missing and the screw locks down on to the crown wheel not the ring. The part is numbered 422  and known as the crown wheel ring. 
    • Just took a look and PUW movements in general has a crown wheel with a small bearing. And by the looks of your ratchet screw I would say it is missing the small bearing and is upside down. I just pop a picture on a common PUW ratchet wheel here so you can see what it might look like.   
    • Crown wheel of course.... screw has no shoulder probably the washer was then lost.  I am learning... very slowly... went to bed 4:15 this morning. I was shocked by the result after the cleaning i guess i must pay the price of the knowledge. Very painful so far and not much knowledge gained, well to my former myself i go with lightspeed but it is just not enough and they say there is no 2 x lightspeed. 
    • 1-Imperfect hairspring coil can foul itself when amplitude gets too high so the rate goes fast , until such time that  HS coil jumps back to normal.  2- Loose and pushed back guard pin, fails to guard the roller table- impulse jewel properly, in which case if the balance wheel gets in a hurry on wrist it is susceptible to the condition in section 1.  Faulty guarding by the pin, can let the condition for sticking to come about.          
    • What you have circled in the picture is the crown wheel and screw. The screw should have a shoulder section to keep it distanced, or a (lost) washer was used there. That is why I wash with petroleum only and IPA only, by hand. And mild ammonia only if there are brass / gilted parts. Then every other thread we read about beginners (but not only) getting fixated on on machines and commercial solutions.
