Can someone recommend a Diamond Paste to remove scratches from an Acrylic, Mineral and / or Sapphire crystal? I see various sellers on Ebay and Amazon, however I wonder if anyone in the group can specifically recommend a brand or reply with a link to the product used.
Thanks in advance for any help that can be provided.
Hello. I recently received my diamond pastes and have had some success using a leather band and microfiber along with the pastes to reduce and (in some cases) remove scratches from the lenses of various watches. I am wondering now how to bring the process from hours to minutes. I want to be able to polish metal bands as well, but glass & crystals are my main focus. I have found that all the rorory tools run at 10k to 35k rpm. I know i need more like 1k to 7k rpm. Are these possible to find? does anyone have other suggestions? I looked into bench polishers. These look great for bands, but i dont have a garage and im not sure this is the best option for removing scratches from crystals and glass lenses. what is recommended for doing this at home? thanks in advance.
Any advice out there for cleaning/polishing watch crystal glass?
I know there are videos upon videos on howto clean acrylic watch crystal glass using toothpaste, Cape Cod cloths, an old toothbrush, etc.
However, I am trying to get a number of scratches out of a watch crystal I have taken the movement out of. It is for me a "tester".
I am fairly sure that this "tester" watch crystal is glass.
I have sandpaper (wet/dry) and I have a Cape Cod cloth which I have just started using.
I think you can see the scratches in question in the pics.
So, what I have done so far is use 400-grit sandpaper to scrub across the grain of the scratches. I have also tried scrubbing in a circular motion.
Maybe I am just not very persistent at this. I scrubbed for some time. But all I can see is that NOTHING is disappearing, and the only thing that IS happening is that now the whole glass is covered in a new set of sandpaper-made marks.
Maybe I can use the Cape Cod cloth to get these out. Maybe I can use the other 1500-grit sandpaper to smooth things out too.
This process looks so easy in the various Youtube videos. yes, I know these things can take time, but HOW LONG?? This is NOT one of the fun sides of watch repair that I am looking forward to doing now or, in fact, any time.
I really thought that it would be the case that - scratches and marks on the crystal? No problem! I can get them out! :)
But perhaps I was naive (?)
How long should I be scrubbing with the sandpaper? Is 400-grit not enough? Should I get more coarse sandpaper?
I usually lay the cap jewel flat side down on a piece of clean paper and rub it back and forth a few times. This will get rid of the residual oil. Next a rinse with lighter fluid and it should be as clean as it can get.
Usually wear on cap jewels is pretty much centered in the middle of the jewel, I suspect its dried up oil. But if the watch is only 2 years old and never been serviced before it should be pretty much pristine! Its a puzzle all right.
Hello all. I have an 1882 waltham 18s sidewinder that doesn't work. Not sure if this is the first watch I should try my hand at. it's a grade 802, has a lever movement but it is in a pendant case or I think so. not sure if these were supposed to be sidewinders set up like this. The stem pops up as well. The watch balance wheel will move back and fourth if you set it at almost a 30 degree angle. if you pick it up or tilt it, it will stop on an dime. with the balance moving none of the hands move. also when you spin the stem in the counter clockwise position, the hands move counter clockwise regardless if the stem is up or down or if the lever is in or out. If you turn it clockwise it acts like it wants to wind, but the hands will slightly move as you do.
Should I try to tackle it or find another non running watch to try my first look see at?
Yes parts are available, but for a complete mov't cost of about USD 100 you will find that most watch repairers will not want to spend time in attempting repair.
BTW, please do no not hook into existing project topics just because you have a same watch. We have a dedicated section for repair questions.
