When you’re picking a watch, what matters more to you: the look, or how durable it is? I don’t know about you, but I’ve personally had that awkward moment when my watch glass gets scratched by keys or the edge of a table. It’s annoying, right? That’s exactly why sapphire crystal is such a game-changer—if you want a watch that can survive everyday life and still look great, sapphire glass is often the best solution.
Common Watch Crystal Materials
Watches come in all shapes and styles, but not all of them use sapphire crystal. In fact, the type of watch glass can make a big difference in durability and daily wear. Here’s a quick look at the most common types you’ll encounter:
l Acrylic: Lightweight, inexpensive, and can be polished—but scratches very easily.
l Mineral Glass: More scratch-resistant than acrylic, but over time it can become cloudy.
l Sapphire Crystal: Extremely scratch-resistant, second only to diamonds in hardness.
Thanks to its durability, more and more automatic watches under $200–$300 now feature sapphire crystal, making it an accessible option even for budget-conscious watch enthusiasts.
What Is Sapphire Crystal?
Sapphire crystal is a man-made sapphire with a Mohs hardness of 9. It’s nearly scratch-proof and commonly found in mid-range to high-end automatic watches.
Overall, sapphire glass stands out for its scratch resistance, clarity, and premium feel. That’s why many watch enthusiasts choose sapphire crystal, especially for everyday watches or military-style timepieces where durability matters most.
Advantages of Sapphire Crystal
l Scratch Resistance: Objects that come into contact with the watch in daily life, such as keys, coins or the edge of the table, will not leave marks on the watch glass.
l Clarity: Sapphire crystal mirrors have excellent light transmittance, and many styles are usually equipped with AR anti-reflective coating to improve the visibility of the dial.
l Premium Feel: It instantly elevates the look of the dial, giving your watch a more high-end aesthetic.

Limitations of Sapphire Crystal
Of course, sapphire isn’t perfect either. Here are a few drawbacks to keep in mind:
Less Impact-Resistant: A hard drop can crack it more easily than acrylic or mineral glass.
Higher Cost: Adds to the watch price.
Slightly Heavier: Compared with acrylic, sapphire adds some weight.
Easily Smudged: Fingerprints and dust show up more easily, so you’ll need to wipe the crystal regularly to keep it looking clear.
Of course, not every situation demands sapphire. For some field watches or military-style watches, sapphire is essential. But for others—like a Speedy Pro or many Seiko models—mineral glass works just fine.
How to Verify Real Sapphire Crystal
Anti-Reflective Coating: Genuine sapphire often comes with AR coating to reduce glare.
Scratch Test: Keys or knives shouldn’t leave a mark.
Look and Feel: Sapphire glass is crystal clear and feels cool to the touch.
A quick tip: not every watch labeled ‘sapphire crystal’ is truly sapphire. Stick to reliable brands and verified specs.
Daily Care Tips
Sapphire crystals are not easily scratched, but they can still crack from strong impacts, so try to avoid dropping or knocking your watch.
When cleaning, it's best to use the cloth that came with your watch; never use paper towels, as they may leave tiny marks.
Also, keep your watch away from hard objects like keys and coins to keep the crystal looking pristine.
