Therefore, once the sapphire mirror was broken, so the maintenance cost will be very expensive, because the watchmakers in the replacement before, must be carefully checked to ensure that the movement was left sapphire. In addition, it is a powerful fingerprint collector, so wipe it regularly to make it bright and traceless. Whether natural sapphire or synthetic sapphire, is one of the hardest substances on the earth, hardness up to Mohs grade 9, in nature, in addition to diamonds, there is no more hard things than it. Notice, this is not in nature, not on earth.
