    Mineral crystal versus Sapphire

    Hello,

    Just as a non-scientific look at this question, I was wondering how important a Sapphire crystal versus Mineral is to the forum members. This is more about purchasing new watches than vintage. And, this doesn't have to be about only the Russians. Just general watch purchases. Thanks for participating!

    Hi Craig ...........

    As we discussed before, to me all things being equal, Sapphire is a 'no-brainer'. With so many manufacturers putting sapphire on very inexpensive watches these days,the cost had obvously come down. I think the benefits of sapphire outweighs any slight incremental rise in cost.

    I also like acrylic (you can polish it). It mineral I don't like.

    Thanks for the survey.

    Unless u like polishing so much and got plenty of free time, acrylic is rubbish and used on those cheap skate watch. It get hair line scratch so easily

    I will prefer mineral glass for lower cost and better shattering resistant.

    Yes, Sapphire is harder but when u drop it, chances of shattering it is higher. Sapphire also cost more to get it.

    I like sapphire on non-military watches. But on military watches I just assume I'm going to wear them rough and scratch them. It's nice to have a mineral crystal so you can get the scratches buffed out!

    Re: Hi Craig ...........

    After hundreds of Watches (some with very hard use) I've never 'shattered' a Sapphire Crystal. I have seriously scratched several mineral crystals though.

    Re: Mineral crystal versus Sapphire

    I prefer sapphire. However if I like the watch a lot otherwise and the price is not super high I'm ok with buying a watch with a mineral crystal. The majority of my watches are mineral.

    To be honest I've never had a problem with scratching a mineral crystal,sapphire is better but I think mineral is durable enough for my kind use.

    I'm OK with anything but prefer sapphire or acrylic (acrylic is easy to keep looking nice!).

    Re: Mineral crystal versus Sapphire

    I have no preference, any type of crystal is good if placed in the right purpose.

    I like a lot the acrylic crystal of the old Amphibia, very thick and solid.

    Mineral or sapphire, it's the same to me, of course a glass crystal that is not easy to scratch is better, but cosmetically they are the same thing.

    Re: Mineral crystal versus Sapphire

    In principle,if I do remember something of my optics'physics, sapphire should be more luminous than glass or conventional acrylic since it has a very good index of diffraction.....
    But since we are in the Russian watches forum, I believe we cannot find sapphire fitting our soviet watches design at afforable prices. Or not?

    Re: Mineral crystal versus Sapphire

    Real Comrades prefer Acrylic!

    It is much less brittle than both mineral and sapphire (very difficult to break even if it deforms under pressure) hence the best choice for military watches.

    It is easy to scratch but very easy to polish!
