Sapphire Crystal vs Mineral Crystal – What’s the Difference?

Every watch is built with a transparent glass known as a crystal, which is a crucial component responsible for shielding the watch dial and hands. It plays a pivotal role in boosting your timepiece’s functionality, from incorporating properties that improve its durability to adding water resistance for dive watches.

It can also set the luxury of your watch, and while there are plenty to choose from in the market, there are two perennial favorites that offer unique qualities: sapphire and mineral crystal. Watch enthusiasts know that there’s always been a debate between the two crystals, and seeing as it takes the brunt of your everyday wear-and-tear, we’re here to settle the score and see which is the best one for you.

What is a Sapphire Crystal?

Leading as the top dog of crystals amongst different watches, the sapphire crystal doesn’t hold back in its sophistication and unparalleled quality, making it highly-coveted in the industry. Luxury brands prefer sapphire crystal thanks to the material’s hardness, which mimics natural sapphire gemstones.

It is made by heating pure aluminum oxide at extremely high temperatures, which prompts the material to crystalize and take structure. Adding diamond-coated saws creates a disk that transforms into a transparent yet premium-looking crystal after it is polished.

What Makes Sapphire Crystal Unique and Expensive?

The upscale prices are not with merit as the production behind sapphire crystal involves an expensive process – starting from pricey equipment, polish, and impressive craftsmanship. Not to mention, sapphire proves to be one of the hardest materials on earth, falling only second to diamonds.

It’s an investment worth taking since its scratchproof and shatter resistance makes it appropriate for any occasion. More importantly, it can withstand heavy forces and everyday abuse on top of looking stunning on your wrist, proving to offer brawns and beauty.

What is Mineral Crystal?

For those looking for a glass that can effectively protect your watch dial from scratches without coming short on its visual appeal, mineral crystal is the next best thing for mid-range timepieces. Most mineral crystals are tempered, which makes it scratch resistant like the sapphire crystal.

It’s also waterproof, but its affordability is what makes it the perfect pick for everyday use. When differentiating between mineral and sapphire crystal, you’ll find that the former has a blue-ish tint, while the latter takes on a pinkish hue.

The Bottom Line: Choosing the Right Crystal For Your Seiko Watch Mod

Both crystals offer distinct properties, but sapphire crystal wins the title as the best choice for your watch when it comes to choosing the complete package. Of course, mineral crystals can do an excellent job at shielding your watch, but it doesn’t compare to the understated elegance and reliability of a sapphire crystal.
