The Real Deal On Mineral Glass Versus Sapphire Watch Crystals

January 29, 2017

Aside from not keeping proper time there is nothing more annoying than a dinged up watch crystal.  Whether it is a long scratch, a fresh divot blocking the date or even stubborn paint scraped off the wall that won't come off with your finger nail.  A flawed watch crystal is much like a noticeable white scrape on a navy blue hull, gorgeous boat but you know.....the gash. Same scenario a scarred crystal takes away from the overall wow factor of your killer watch.  This is why it is important to consider which raw material to invest in, mineral glass or sapphire,  Let's define each:    
Mineral Glass- Made from silica, mineral glass is just that, old school glass.  It is a step up from mass production watch brands that mostly use acrylic (plastic) infused glass to cut production cost.  Mineral glass is more pure, structurally harder and more difficult to scratch than acrylic.  It ranks 5 out of 10 on the official MOHS Scale Of Hardness.  
Sapphire- Ranking 9 out of 10 on the same MOHS Scale Of Hardness sapphire watch crystals are as close to indestructible as you can find.  A diamond and perhaps some choice industrial power tools are the only things that can nick your premium sapphire watch crystal.  Toughness, durability, long life span are what makes a sapphire based crystal a must have specification for your hardcore offshore timepiece.    
All SEATEK watches are built standard with industry leading sapphire crystals but we take it a BIG step further.  Our collection also features Anti-Reflection (AR) treatment applied to the sapphire preventing reflected light and glare while enhancing the aesthetic of the crystal surface, very cool stuff.  To conclude in the watch game there is the best of the best and then there is "everything else".  SEATEK watches delivers our customers the finest in materials, components and USA craftsmanship leaving "everything else" to the amateurs.
