Generally, polyWatch fills in the scratches. PolyWatch is a repair tool for watch scratches so the blur is a side affect. I have not tried using polyWatch on my lenses so don’t take my word for it but from what I know it shouldn't intentionally cause blur. When you are done, it will leave your acrylic or plexi crystal flawless and free of scratches, allowing perfect legibility onto the dial. The benefit of this is that you don’t have to replace your whole watch crystal in case it only has scratches. This is both a cheaper and more effective alternative. I owned the same type watch years ago. I had same issues. I polished off AR coating with Polywatch, and it took a great amount of time and effort. I believe there should be a post/thread on this topic, specifically for PO.

I'm curious about Polywatch, or any single product for that matter for a full crystal polish. I assumed that to get a good polish (ranging from scratch elimination all the way to a high shine), you need to progressively decrease the It looked very similar to your watch. It took me about 45-60 minutes and I was rubbing the crystal using polywatch really hard using the cloth that came with the polywatch. Would never rub it that hard on a hesalite. With the included polishing cloth, rub in a circular motion, with firm, constant pressure. The heat from the friction will allow the Polywatch to smooth out the crystal's surface.

As with all polishing, move through grits from coarse to fine, making sure that you remove all of the previous marks before moving on, and finished with Polywatch. Please excuse the dust... Polywatch is so mild an abrasive I have never bothered to tape off anything and I just make sure to keep the cloth with the polish on it on the crystal alone and not rub the Polywatch on the remainder of the watch. Some toothpastes might work. We used to use Gleem over here when I was a kid. Don't know if Gleem is still sold. It was pretty abrasive. Such a toothpaste might be harsh on a watch crystal. I haven't encountered any similarly abrasive toothpastes in some years. The polishing process is the same no matter what you are polishing typically, so an acrylic crystal, metal, etc. makes no difference to what the process is on the most basic level - replacing larger scratches with progressively smaller scratches. One tube of PolyWatch can be used for approximately 10 watch crystals (depending on how much you use and how deep the scratches are).

I believe that AR coatings are only applied to the inside of the watch crystal. If this is the case, then the scratches you are seeing are not to the coating, but to the sapphire itself. Sapphire is incredibly hard to scratch (bravo for finding a way to scratch it), but that also means it is equally as hard to polish.

Sometimes you will notice that the crystal will look better 24-48 hours after treatment, than immediately after application. That's because you've given the fresh melted plastic a chance to harden. i just use a generic "polycarbonate headlight polisher" from pep boys or so - I had sitting around in the garage ... works just as fine ... never had a scratch that I couldnt get rid of What Polywatch (or any other similar product) does is to use a super-fine grit to create enough friction to allow a tiny amount of plastic to melt into the scratches and fill them in.
