Not every watch is the same, especially when it comes to the crystal. You'll often see terms such as sapphire crystal, mineral crystal or acrylic crystal in the specifications. But what do they actually mean? And more importantly, what difference do they make in everyday use?

Whether you choose acrylic, mineral or sapphire, each type of crystal has its own advantages and price range. The most important thing is understanding what you're buying and choosing a watch that suits your lifestyle. Are you someone who enjoys sports, travels frequently or simply wants a practical everyday watch? Then a few scratches may not bother you. If you'd prefer your watch to look like new for years to come, investing in sapphire crystal is well worth considering.

And if something does happen, you're always welcome at Kish for crystal replacement or watch repairs. That way, you can get the most out of your watch without any unpleasant surprises.

Types of Watch Crystals Explained

Acrylic Crystal (Plexiglass)

This is the most affordable option. Acrylic is lightweight and easy to shape, which is why it's commonly found on entry-level and sports watches.

Disadvantages: It scratches easily.

Advantages: Most scratches can be polished out with ease.

A great choice if you're looking for an affordable watch and don't mind the occasional scratch.

Mineral Crystal / Hardlex Crystal

By far the most common type of watch crystal. Mineral crystal is harder than acrylic, making it more resistant to scratches. It's affordable, clear and gives a quality appearance.

It can crack or shatter if subjected to a hard impact, but for everyday use it's an excellent and reliable option.

Sapphire Crystal

Sapphire crystal is considered the king of watch crystals. It is almost as hard as diamond, making it extremely resistant to scratches.

You can wear a watch with sapphire crystal for years without developing the haze of fine scratches often seen on other crystal types. It costs more, but offers luxury, durability and exceptional clarity in return.

Which One Should You Choose?

At Kish, you'll find watches featuring every type of crystal, making it easy to choose the option that suits your needs:

  • Budget-conscious or casual wearers: Acrylic or mineral crystal.
  • Everyday use: Mineral crystal for added durability.
  • Luxury and long-term enjoyment: Sapphire crystal, the most scratch-resistant option available.

Use the crystal type filter in our webshop to quickly discover watches that match your preferences. And if anything ever goes wrong, we'll ensure your watch crystal can be repaired or replaced quickly, professionally and at a fair price.
