⌚How to check if your watch has sapphire or mineral crystal with and without tools? Watch tutorial⌚

Unfortunately, the drop test is not 100% reliable… checked it on a Submariner and Tudor GMT at my local Rolex / Tudor ADs - the water sometimes beads / sometimes spreads…

I normally use car key or a sharp blade 😂

Hey! wait a min..
Water drops on my cheap-O Vostok and HMT are staying as bubbles..
Maybe someone in the factories made a happy mistakes and slipped in the wrong crystals.. yay!
Or perhaps, there are more variables that effect the surface tension, and this test is unreliable.
I'm going with happy mistake..

PS, anyone want to buy some sapphire crystals?

I have a Seiko sapphire crystal and it is very cold until it warms up . Since it’s not metal,, how does the heat from the titanium transfer to the glass, which I thought was an insulator

Thanks!

If the glass is impossible to see through in certain angles under water. Would that be a tell tale of any of the things described in this video?

Thanks for the info

sadly if the glass have oleophobic layer, you will not know nothing checking with water drop test :(

i thought Saphire Crystall has the benefit of no sunlight effect while checking the time ? never heard about water drops o.o

Surely the anti reflective coatings will affect how water droplets sit.
And for 'coldness' surely that has to do with thermal inertia, so a thick mineral glass would appear as cold as a thin sapphire?

helped a lot! My $100 aliexpress watch has sapphire! (probably lab grown)

Kada si izbacio pre nekih 6 dana video sa kupujem prodajem za parfeme trazila sam marina bg ali nigde ne mogu da nadjem

I never shattered sapphire glass but it happened a few times with mineral glass watches.
