VRWOX [2-Pcs ] For Casio GST-B300 G shock Watch Screen Protector,2.5D Rounded Edges 9H Premium Real Tempered Glass Screen Protector Anti Scratch,Anti-fingerprint Bubble-free

The Casio GSTB300 watches do not have the large protective bezels that most G-Shock watches are known for so it's smart to protect the mineral glass from scratches. This tempered glass looks like it'll do the job just fine.PROS:Inexpensive way to protect your watch.Glass, not film.Goes on easily.No bubbles form under the glass.Comes with 2 protectors and the cleaning supplies for both.The edge can be seen but you'd have to look closely. (See photo)CONS:No instructions except for this ad on Amazon but easier to install than a phone protector.

I just wanted to give this a quick review even though I ordered the wrong size for my watch - so make sure y you check the size. Overall, I have no complaints with this set, it's pretty much the same quality as any cover set for phones, tablets, or watches that you can get anywhere. The price is fair, and I know from experience how important it is to cover and protect your watch face, especially if you are active outdoors and in the woods like I am. I will have to try and get another one that actually fits my watch so again, measure first! If it is the right size than I think you will be pleased with the product.

I have used screen protectors off and on for years. I have tried both the plastic film protectors and the tempered glass such as these protectors. These work as advertised and are so easy to put on (be sure to remove any film the watch manufacturer put on, some are pretty hard to see). This protector fits many watches besides the one in the advertisement.
