(Pack of 4) Tempered Glass Screen Protector for Casio MDV106-1A, Akwox [0.3mm 2.5D High Definition 9H] Premium Clear Screen Protector for Casio MDV106-1A

Work like cellphone screen protectors. Just be sure to scrupulously clean the surface before application, and use the lint lifting stickers.

Easy application, adheres well to watch face. I beat the hell out of my watches. I work outdoors on swimming pools and equipment, so alot of knocking, scratching, submersion, dropping, etc. I need a quick glance on my watch alot- visibility on this protector is great. Amazon had a low price in Duros, so I got a couple. I dropped one of my duros on my hardwood floor, a wood floor, scratched the face, then bought these protectors. They aren't the tightest fit up to the bezel, I thought I would want a larger protector that went to the very edge of the crystal, but went a head and put these on. I bought a slightly larger protector- same brand, but they were too large and overlapped the bezel. I saw these with the Duro pic and decided to try these. But, these fit very nice. I think the angle transition from bezel to crystal make these more gradual. I think a larger protector would actually catch more knocks and dings- chipping the edge or even scraping it off. The edge of the protector is slightly rounded, so even though it adds to the crystal height past the bezel, it doesn't snag or grab glancing objects. It is near perfect, it does protect the crystal and I forget its on. Perfect would be Casio putting a much harder crystal on their watch, which I think has been discontinued. No scratches since I put it on. And they give you 4... I guess I could buy more duros...

After the first couple of scratches on my Marlin fave, I started hunting for protectors. Review convince me that these we a good choice and I have had no reason to disagree at all. They go on easily and across half a dozen I have had no problems with bubbles or centering. They are crystal clear, to coin a phrase, and when you take one off to replace I you can see that they save the face from a lot of abuse. I'm not even that active, at 76, and I still use 2 or 3 a year. They're great. Buy a bunch and protect that face!

The product is difficult to centre, however, that can be worked around. The problematic part is that the tempered glass protector is too small to cover the entire crystal.

These are slightly tricky to get installed perfectly centered on crystal, but are totally invisible once installed and work great to prevent scratching of mineral watch crystals. Fantastic addition to the great Casio Duro watches. Cheap enough that they are easily replaced if cracked or scratched. Everything you need to clean and prep your watch is provided (except a steady hand). You probably have a screen protector in your phone just like these. Same deal.
