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. Usually I use masking tape around the bezel and edges to protect them. This is very important for gold-plated or filled watches as the chemicals tend to get underneath the plating and react with the base metal of the case. old t-shirt .... moisten lightly with some finger's worth of water until it results in a "wet-spot" (insert dirty joke here) ... then a bit of the polish (fingernail sized drop) ... then I gently work the mustardy-paste into the wet spot until all the excess is in the fabric (about 2-3" across).

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. 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 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. Plastic watch glasses scratch very easily and replacement is not always possible, particularly where the case is plastic. Polywatch slightly disolves and grinds down the surface of the plastic watchglass to smooth the edges of the scratch and fill the gaps with dissolved material. PolyWatch is a cream that contains a very light abrasive material that will gently but effectively grind down your acrylic/plastic watch glass crystal, resulting in a scratch-free finish.I will sometimes, depending on the watch, use a coarse as 400 grit to start - all done by hand and you do need to be careful not to overdo it. It looks worse before it looks better: No matter how careful you are, plastic watch glasses will scratch over time. This is mainly due to the position of the watch on the wrist, where it can easily scrape against a wall or other object. Unlike glasses, these scratches only detract from the beauty of the watch and not its function. However, it is annoying to constantly look at it. The product 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 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 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.

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 and start seeing results, wipe off any residue from the crystal. You can do this with a clean cloth. Polywatch is for removing fine scratches so the scratches have to be minor, or it's used as a final polish. Trying to remove large/deep scratches with it is not really the proper use. If the scratches are deep enough, you will just make them shiny rather then remove them. Using Polywatch on this for example, would be mostly useless:PolyWatch is a simple and reliable solution against scratches. The unique PolyWatch paste, which has proven itself millions of times, even removes deep scratches! It is not without reason that PolyWatch is the number 1 worldwide when it comes to watch polishes for acrylic glass. The innovative plastic deformation technology, which slightly softens the clear lacquer on the glass to fill in damaged spots, polishes away scratches and blemishes in an instant. Instructions 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. not to diss polywatch ... but I bought a bottle of "generic poly carbonate headlight polish" ... big ass bottle for 0.99 ... its the same - works the same 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.
