Sapphire replacement crystals for your Seiko.
Sapphire crystals are the perfect replacements for your Seiko watches,they are very hard wearing so you are much less likely to scratch or damage them and the clarity of the crystal is second to none. The base Sapphire material is often Swiss sourced so the quality is superb.

Sapphire (whether natural or synthetic) is one of the hardest substances on earth. It measures 9 on the Mohs scale, which is a system for rating the relative hardness of various materials. (Diamond measures 10, the highest rating.) Watch crystals made of synthetic sapphire are often marketed as "scratch resistant", meaning they are very difficult - but not impossible - to scratch. Diamond can scratch them, so can man-made materials that incorporate silicon carbide, with a Mohs rating of between 9 and 10 very like diamond and harder than sapphire.
