Plastic Lens Scratch Remover

I bought this for a five year old watch that I stopped using 18 months ago because the face was so badly scratched. Recently the band broke on my new watch and while I decide on a replacement band, I'm using the old watch, but the scratching was just too bad to tolerate. I was skeptical about Polywatch, but it actually works.I see a lot of reviewers reporting that it doesn't work. I suspect they didn't read the instructions carefully. They are hard to read, just very small print in five languages on the side of the small tube.Polywatch works by rubbing the watch crystal for two or three minutes with enough pressure to generate heat. The heat melts the surface of the crystal, which mixes with the Polywatch and fills the scratches. It really works, but you have to work at it, and you have to rub at right angles to the scratch. In my case, this meant rubbing the crystal several different times, each time in a different direction. It didn't remove all the scratches, but they are no longer visible unless I'm holding my watch really close to my eyes. I suspect I could have removed the rest of the scratches, but it wasn't worth it to me. The watch looks fine now when viewed from a normal distance.The directions recommend using "cotton wool" for rubbing the Polywatch into the crystal, but it wasn't my local stores and rather than wait to order it over the internet, I used an old tee cotton tee shirt. It worked fine.Some reviewers complain about the small size of the tube, but I used only a very small quantity. The manufacturer says it's good for ten watches, but even my very badly scratched watch required so little Polywatch to remove scratches that it's likely to last for more than ten watches,Usually when writing reviews, I also point out the negatives, but I can't find any with Polywatch other than the tiny print of the directions.A word of caution: I've read conflicting opinions about how Polywatch works on vintage watches. Before using it on any vintage watch, research it to see whether Polywatch is likely to improve it or make it worse. Some alternatives to consider are Brasso or even toothpaste, which some people use for removing scratches from watch crystals. I've never tried either of them.

I had high hopes, but this product is totally bogus. It is a polish, as stated on the front of the tube.The directions say, "Apply PolyWatch to the plastic watch crystal. Polish the scratched areas for 2 to 3 minutes with pressure using a piece of cotton wool. Deep scratches need to be treated more than once."I've got news for you. You could apply, re-apply and re-apply again til doomsday, and it ain't doing a darn thing to remove the scratches, no matter how shallow. Tried it on a watch and on reading glasses. No impact whatsoever.

I have a watch or two with plastic/acrylic/etc "crystals" in them that were really scratched up. A simple a cost friendly fix was to get some PolyWatch that I've heard about from various sources.For this review I used an older Seiko automatic that I recently purchased off of eBay for cheap. The glass or "crystal" was really scratched up so I thought it a perfect candidate.After receiving the tube, I sat down with some Q-tips and paper towels on a desk. I set the watch down and squeezed some on and buffed with a Q-tip/cotton swab for 3-5 minutes (re-applying a little paste every minute or so).After that first session It was hard to tell if it had worked, but the watch in question was pretty badly scratched and dinged up so I went another 5-10 mins. After that I could definitely tell a difference - the deep gouges and scratches were much less noticeable and the dial more visible. I went another 5-7 minutes before calling it a night and was surprised at the before/after photo comparison.I'd say in total I buffed this 1 watch crystal for about 20 minutes, re-applying paste often. I'd guess I used about 1/4 of the amount in the tube. I will say, the tube is not 100% full from the start - Holding it up to a light you can see about 60% of it contained product. For the higher cost for such a small tube, consideration should be given to how much is used and on what projects. It IS cheaper and less hassle than replacing the crystal though.PROS:- It works. May take several coats and some elbow grease to really get deep scratches and dings out.- Comes with nice little fabric swab that seemed to work well with the paste.- Cheaper than replacing the crystal.CONS:- Small tube for how much it costs. Expect 2-4 good uses from this 1 tube for deeply scratched crystals.- Tube comes filled with a lot of air - package size can be misleading to how much content is inside.*Photo attached shows "Before" photos on Left side, "After" photos on Right side. Watch has a few spots and dust specks inside crystal so some of that isn't the crystal.
