At long long last, I have figured out how to remove all the scratches from a pocket watch glass crystal.

1) sanding disk on a dremel tool at setting of 20.

2) just go back and forth until all the scratches are gone. Used 240 grit disk at a fast speed = 3000 grit.

Is the photo in the bottom center the finished product ? I can still see some lines. Should try some toothpaste or polywatch to completely remove those lines.

Will do, but it was night and day. Btw, poly watch does not work on glass crystals

Correct. Not all abrasives are created equal, so you got no haziness left by using such a corse grit.

Ah wait, sorry, I forgot that you mentioned glass and not acrylic. Yeah you're going to need some diamond paste or maybe more cerium oxide...

With my limited knowledge I have found a quick & effective way to remove minor scuffs & scratching from my "plastic / acrylic " watch cystals......crystal stays in watch case. I use a fine grit sandpaper.....not sure but believe 225U.....very fine....... I wet crystal with a few water drops & by hand do circular & cris cross, maintaining moisture, clear residue & repeat 3 or 4 times, always with moisture. 

This leaves the "plastic / acrylic " crystal with a hazey look. I then use toothpaste....put a small dab on dry face cloth & take watch crystal & with some pressure pushing down into face cloth , toothpaste.......hold section of face cloth tightly & rotate crystal side down circular movements for about a minute (....area drys up....) Repeat a couple of times & clean crystal with damp cloth. I have had good successs geting very clean & clear crystals......but will leave marks on face cloth you use.......really upsets the wife.....

Hi You can achieve the same results without the we & Dry  using Jewelers rouge or Autosolvol  a car chrome cleaner.   Use the rouge (red Powder) on a dampened cloth and plenty of elbow grease for both methods.            Please dont use the face cloth you will get Horology a bad name:D not only that but it could lead to banishment and sharing with the dog.

I have actually improved the process by using a 600 grit sanding barrel. No lines. Then finish off with this stuff....works great on glass.3824be196e597be66d6be8f7759a2007.jpg

    • so now we have the ultimate? How do we deliver it?  
    • Russia is member of the Universal Postal Union and as such their Post must accept pieces for any destination. International tariffs link https://www.pochta.ru/documents/10231/726549028/УУС+2021_.pdf/ Interstingly unlike hey do not group destinations by listing orcontinents but by distance - however measured.  Then any individual seller is free to decide where they do ship and where not. I suggest that you contact the seller and inquire, he may be just be unfamiliar with remote destinations prices. 
    • I don't get your point. If you make or maintain a measurement tool, of any kind, you need a reference for calibration or just validation. It can be more or less accurate but it has to be there, that's metrology 101. You can have all the atomic clocks and Network Time Protocol to disseminate time, the issue is how to bring that accuracy to a standalone device and know if it is reliable.  Otherwise one can get into watercolor painting or other interests that do not require that kind of approach at all. 
    • Material houses like cousins, eslinger, ofrei, julesborel do carry watch parts, though I doubt you can find a sign crown for this. Familiarize with  Dr ranfft's very popular database for good general information on most calibers, just google ETA 1260 ranfft. Good luck
    • You can use any crown of your liking and that matches the pendant tube. Since you haven't posted pictures of the case one can't tell how it should like.  Two piece stems are easily available, even on Ebay.    As answered sometime. In the past service manuals did not exist because the watchmaker was supposed to known his trade well enough.  Parts lists were issued to ease identification and ordering, very many including for the one you have can be downloaded from Cousins UK.
