sharkey_lsu 0 Posted January 19, 2011 I received my first rep yesterday...omega speedmaster pro from Mary (amazing dealer) and I believe it has a sapphire crystal, but how do I differentiate between the two? Share this post Link to post Share on other sites
narikaa 129 Posted January 20, 2011 Water drop test (sapphire congeals it to a droplet, mineral smears it out flat) but some coatings can corrupt the outcome Some say they can tell a difference in temperature between Sapphire & mineral when pressed against forehead (then again some people say they see dead people) Or use an electronic diamond tester (it should bleep like a good'un if sapphire) But if its so difficult to tell them apart...is it really that important .

I just did the water test and compared it to my old watch which i know is glass and it was obvious that the new one is sapphire. Thank you!! Share this post Link to post Share on other sites

bazguitarman 0 Posted January 20, 2011 I have a Seiko dive watch (I know, not a rep.) with their propriatary "Hardlex" mineral crystal. It is scratched all to hell and back. Most of the scratches are of the "nail catch" degree. Now, admitingly I'm a door banger. But the poor watch is looking pretty bad. IMO, it scratches very easily and to such a degree that I'll just pay extra for sapphire from now on. I'll be buying a steril 44mm from Getat and a U-Boat Flightdeck rep from my income taxes. Both with sapphire crystals. So I think I may retire this watch till I can have the crystal replaced with a sapphire piece. I'm no expert, but if sapphire is any better than mineral that's the way I'm going from now on. Eric Share this post Link to post Share on other sites

offshore 0 Posted January 20, 2011 BTW if your mineral [or sapphire for that matter] crystal does scratch it can be buffed out with Diamond Paste, you will need a 3 Micron Paste [around $13] and a 0.25 Micron [around $13 also], using the 3-Micron you polish the crystal with your finger for 3-5 minutes and then finish off with the 0.25 Micron for another 2-3 minutes, et voila! Just a friendly reminder from your friendly neighborhood Pyromaniac. And even better, you can get a sapphire polishing kit with both of those diamond paste grades in it for probably 1/2 that price from the RWG shop. Ask Col about it.

d1isthe1 0 Posted January 20, 2011 Three of my pieces are in sapphire and two in mineral including the dssd for which I will go for a sapphire.. The cheapest I have is a Tissot V8 (amazing dial) which has a sapphire and I take it places where it is put thru a lot of abuse... But till date there is not one scratch on the sapphire though the casing has many on it.. I wear my watch in my right hand hence it usually collides with lot of things and watches of friends when they are on my right. Sapphire it is then...
