ZshionZshion (2 Pack) for Casio PRG-600/650 Screen Protector,9H Hardness Tempered Glass Screen Protector for Casio PRG-600/650 /6600 with Anti-Fingerprint Bubble-Free Crystal Clear

Came as 2-pack tempered glass, adhesive side with a labeled peel-off, and usual wipes. Install went great, not a single bubble and no debris. The fit is exact, meaning it covers all of the watch face, but does not extend onto the bezel. It appears to be absolutely clear and doesn't seem to slow the solar charging. See photos, its thickness makes it such that it is just a bit higher than the bezel, but likely wouldn't be very protective if it were thinner. It's only been on for 2 days. I'll update this review if any problems later.

The protector fit perfectly on my PRG-600 watch. The instructions are for a cell phone and on the back of the package in small, faint print. I have some on cell phones so that experience helped get this one on correctly. I had no bubbles at all. No sure about how it will last.

Very easy install! I was a little skeptical about the price and how much value you're getting for this price, but when it comes to protecting your watch face it is a small price to pay. I love when protectors come with the guide stickers for easy installment, it just makes the entire process simpler and you get a near perfect application. You can't even tell you're looking through more glass, it is very clear. I will do a review again later down the road to see how it holds up.Update: I had this on a watch while hiking and smashed the watch face into a rock wall. I was pretty disappointed to see it cracked BUT when I took the glass protector off it was only the protector that was cracked, not the actual watch face! I would highly recommend this product to anyone looking to protect their watch.

Of the many experiences applying screen projectors, this was the best. The kit includes everything needed and, very importantly, location tape strips. These allow you to locate the screen using the strips like a hinge. You then lift the edge and remove the backing. The strips allow the protector to be lowered carefully back to the same location. I didn't see this technique in the directions, but it was flawless. I used the included cleaner and tach sticker to remove any debris.The glass appears to be very good quality and Looks like the crystal. It looks like it was made that was originally from the manufacturer. If it holds up over time, it'll be an incredible addition to the watch.

I guess the point is to break the protector and not my watch crystal. They do protect the crystal, however I break the protector within about two days.

The crystal fit perfectly and looks great. It's Crystal Clear and only extends a fraction of an inch above the bezel of the watch. The edge of the bezel is slightly radiused and polished. Everything needed to install the crystal is included, including alignment stickers, cleaning cloth, drying cloth and delinting sticker. Highly recommend this purchase.

They seem to be holding up fine, it’s only been a month but the quality seems decent to me. Would definitely purchase again, as it stands.The first set I ordered the 2 piece glass protectors were missing, which is strange because the case was sealed, slightly annoying I returned that order and bought another.

Can't even tell this crystal protector is installed
