YounikerYouniker 3 Pack Universal Round Watch Screen Protector Tempered Glass, 39MM Generic Watch Screen Protector Foils Glass 9H Hardness 0.3MM Slim, Anti-Scratch, Anti-Fingerprint, No Bubble (39MM)

Ordered a size smaller as recommend by seller but it was too small and left a noticeable gap around the watch face. Returned and re-ordered the size as per my measurement and the glass was a perfect fit and it’s impossible to tell there’s a protector fitted. Product itself seems robust and undamaged so far. If it does get broken or scratched then that’s what it’s for- there are another 2 in the pack.

Awful things, I always apply screen protectors to devices and consider myself competent in doing so, I've never been unable to apply one before, have had glass protectors on flat and curved devices before without issue but I used up all 3 of these and none would adhere evenly across the entire screen, all 3 had a patch that wouldn't adhere, usually the last part to touch the watch face.These were well sized for the watch and the screen is dead flat, so not a compatibility issue - these just didn't work.Threw them away and ordered a different make, worked first time.

Firstly, these came without instruction. It's a fairly self-explanatory process for anyone who's applied a screen protector before to their phone, for instance, but some guidance wouldn't have gone amiss.More importantly, the tempered glass has no adhesive surface once the protective layers are removed, hence it does not stick to the watch face.I'd advise against buying this product.

Despite some previous reviews I found that this item fitted perfectly with no problems at all. No instructions with the item but easy to follow ones are on the Amazon site. It is almost impossible to tell it’s there and the touchscreen is not affected at all. Overall very good product.

These are great, fit my watch perfectly (rotary skeleton watch) the glass case adheres the the watch sapphire well. I am quite a clumsy person and hit all sorts with my watch, but these have protected the screen well! I've got my watch very hard twice, cracking the screen protector, with absolutely no damage to the watch! Easy to replace with the spares in the pack!Great product, my watch has a flat screen not a convex one

Bought for a Ticwatch Pro 3 GPS after another company let me down by sending the wrong size. Fits right across from bezel to bezel protecting the entire screen. Easy to apply too.

Terrible product. Watch face is 40mm so ordered the 40mm product which arrived far too big. Tempered glass was completely flat and rigid so couldn’t be pushed against the face properly. But the worst thing, the glass wasn’t sticky at all - it fell off the watch face a few seconds after placing it. Find it very difficult to trust the other reviews that say it works well. Have just returned for a refund - terrible quality and a waste of money.

Awesome! Easy to use and you don't even notice that it's on. It's good that you have two more just in case anything goes wrong.
