Maybe it's sapphire coated but that's about it in my opinion.
For starts it's just a dull looking crystal & I have to wipe it 4 or 5 times a day to keep it clear (no I don't do anything messy or mucky to get it this way)
Like most of you I have quite a collection & have owned probably over 50 watches over a long time & other than acrylic crystals (sometimes) I have never cleaned a crystal so much.
So in my opinion they are not Sapphire. Who know's maybe I got one that wasn't fitted with one if they ran short on a batch but like I said I'm happy with it for the money & if I decide to keep it I will fit a Domed Sapphire. Sent from my SM-N960F using TZ-UK mobile app

Measures the crystal-gemstones heat conduction rate.
Their are so many fake Tissot watches out there I would of either taken it back & exchanged it if you bought it from an official dealer. But if it was eBay or some such place it wouldn't surprise me if it wasn't real.

Fyi a hardened steel screw or razor blade will scratch mineral glass but not sapphire-corundum with no ar exterior coating.
Tested. And I hold my hands up I couldn't scratch it with a razor blade so maybe it is sapphire after all.
I pressed as hard as I could & scraped all over & nothing. Not even a hair line mark.
Gonna try with a hard screw tomorrow
Still going to replace it tho. But yes assuming it beats the screw I will 100% eat humble pie. Sent from my SM-N960F using TZ-UK mobile app
I recall buying a Phoibos watch and that had a sapphire crystal but exactly as you said it was very dull and the same had to keep wiping it, I returned the watch but often wondered why it was so dull and murky when looking at the watch dial. Maybe you have answered my question, thanks
I suspect the difference you've seen is more down to AR coatings on different brands than Sapphire or not.
My Breitling looks as though it has no crystal at all, but other watches (Sinns, for example) are more prone to marking. I didn't buy those from eBay, before you ask...
I'm not sure, either, how you're going to guarantee your Domed Sapphire will be any more authentic...
