Strictly speaking, Sapphire crystals aren’t really Sapphire. The correct name for the material is corundum. Sapphire is used to describing the blue variety corundum, while ruby is used for the red variety.) A Sapphire crystal is a lab-grown crystal that has the same properties as a Sapphire; which rate a 9 on the Mohs scale of hardness. Diamonds which are the hardest substance on earth rate a 10. This crystal is then cut and polished and placed as the lens of the watch to protect the hands and dial. Sapphire crystals, which are often coated with an anti-reflective substance, are the hardest lens used on watches and are very difficult to scratch. The time consuming and labour-intensive process used to create and finish these crystals to exacting standards add to the rarity and value of a watch with a sapphire crystal.

A screw-down crown helps protect your watch from moisture and dust. While wearing the watch, the crown should always be left in the locked position. Release the crown by turning counter counter-clockwise (down toward the 6 o'clock position). You will then be able to extend the stem in order to set the time, date, day, etc. When finished setting the timepiece, lock the crown back in place. Make certain that the stem is pushed all the way in, then apply light pressure and turn clockwise (up toward the 12 O’clock position) until the crown tightens into place.

To set the day, gently pull out the stem halfway. Turn the stem counter-clockwise (down toward the 6 O’clock position) until you get to the desired day. You can only go up in days not down. After you have reached the desired day push the stem in all the way.

Diamond bezels are available for certain models. It generally takes 6-8 weeks for the bezel to be made. Pricing is based on the price of gold and diamonds. Please call for an estimate.

In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat exponential.
