    Whats the big deal with sapphire crystals

    It looks like everyone and their mother wants to replace the regular crystals with a sapphire crystals what gives. The only thing I know about sapphire crystals is that they are harder.

    I think Sapphire is good but having watches with hesalite and sapphire, i have no doubt that sapphire picks up fingerprints more easily. All types of crystals have their strengths and weaknesses and sapphire is no different.

    Sapphire is a great material to make crystals out of, sure for.
    However - in some situations, crystals such a hesalite prevail (in space for example). But, as we don't tend to go to space too often, the mass markets tend to prefer sapphire because it is scratch resistant etc..
    In other words, it'll put up with rough treatment well.

    cheers,

    One thing I have always wandered...

    Sure sapphire is much more resistant to scratches, but that doesn't say anything for the rest of the watch - sure the crystal won't get scratched if you knock it, but the rest of the watch will still take a beating...

    Sapphire's high scratch resistance is what the big deal is. Now that doesn't mean it can't scratch, but it is very resistant to it. Acrylic scratches easily, but can be easily buffed out with something like Polywatch. Mineral crystal or hardlex is in the middle, but is a pain to deal with if it does get scratched. You can't easily buff it out and often times you may need to swap the crystal.

    Re: Whats the big deal with sapphire crystals

    Any material used for a crystal has tradeoffs. The sapphire crystal is indeed more resistant to scratches than other materials. It can under certain circumstances shatter easier because of it's usually desirable hardness. Sapphire crystals tend to be be more visually active in light which some owners actually like. Many watch companies coat one or both sides of the crystal to dampen those reflections. The optical coatings are somewhat fragile and are subject to showing visible wear. I'm wearing a 1980 (thereabouts) Aquastar Atoll in a non-steel (titanium?) case and sporting a hesalite or similar crystal. I feel no urge to replace the crystal on that classic diver with a modern sapphire one. Unless one bumps up against brick walls regularly I don't really see the need to change crystals. The presence or absence of a sapphire crystal would not be a deciding factor for me when buying a watch.

    There is nothing special with sapphire, it's just an industry standard to boost sales, it's always good to know that your watch has a lot of jewels inside and sapphire on front and back.

    Due to the popularity of affordable Japanese watches with Hardlex and their low price, Hardlex is seen as a cheap material, even Chinese watchmakers (e.g Seagull) use sapphire for most of their watches now.

    I tend to disagree. I have a 6 year old Tag with sapphire. While the case shows a lot of signs of wear, crystal is spotless and as good as it came on day 1. I have a Seiko diver with hardlex which is 4-5 month old and already has 3-4 big scratches. I love that watch for what it is. But it's my last hardlex for sure.
