I have hit the crystal of my Rolex on block, brick, and other hard surfaces. In 24 years not a single mark. I am amazed at this material and its survivability.
Hi Cam, Your lecture was direct and to the point..watch repair has become a dying art..,which is very sad...your studio workshop in beautiful.. Ty for the lecture..great job.😊
When examining a watch to see if it's counterfeit and looking at the date through the cyclops on the crystal, the date on a fake can appear smaller than on the genuine watch. I suspect this is partly because the counterfeit has a mineral glass crystal & cyclops that's cheaper than the sapphire on the real watch. Glass has a lower index of refraction than sapphire, thus less magnification.
Finally had the time to watch this! I like acrylic crystal exactly for that reason! Scuffed? No problem! It buffs right out! Is it true that mineral crystal has more flex capability than sapphire? I have also seen watches that claim to have sapphire coated mineral glass. Does it then have both characteristics like for example it won't scratch but the top layer could shatter... Just curious as to why and how that would work! Thank you for the great series! It's been really informative! 👌👌
I would imagine the sapphire coated mineral crystal is a little better at resisting scratches than uncoated mineral glass without adding much cost to crystal. Would not change the overall hardness of the glass though.
When trying to identify a crystal's material, it seems if you can sight all the way through a flat crystal sideways, like when some of the bevel is above the case, mineral glass will be faintly green and sapphire will be faintly violet. I figure this is due to an acceptable amount of normal impurities and a manufacturer can override the color, as in the green sapphire crystal in some models of Rolex Milgauss. Perhaps they add a little copper to their mix.

Your video is great again! Apart from the great lecture the editing, the music, the high quality is outstanding.

TIL sapphire crystal is only bested by diamond. wow.
I personally like acrylic or sapphire. Mineral crystal is the least appealing to me.
I agree with you completely on that one.
