The watch crystal, also sometimes referred to as the watch glass, is the transparent component on the front of a watch that protects the delicate dial and inner workings from dust, moisture, and scratches.
It acts as a window, allowing you to view the time and any other complications (additional features) on the watch face. But watch crystals are more than just a piece of glass – they come in various materials, each with its own advantages and disadvantages.
Types of Watch Crystals
There are three main types of watch crystals used in watches today:
Acrylic Crystal (Plastic): This is the most affordable option. Acrylic is a lightweight and flexible material, making it less likely to shatter upon impact. However, it’s also the least scratch-resistant, and scratches can accumulate over time, making the watch face less clear. Acrylic crystals are commonly found in budget watches and children’s watches.
Mineral Crystal (Glass): This is the most common type of watch crystal. Mineral glass is a harder material than acrylic, making it significantly more scratch-resistant. It’s also more resistant to shattering than acrylic. However, it can still scratch if impacted by something hard, and it may shatter upon a significant impact. Mineral crystals are found in a wide range of watches, from mid-range to some high-end models.
Sapphire Crystal: This is the most scratch-resistant type of watch crystal. Sapphire is second only to diamond in terms of hardness, making it highly resistant to scratches and shattering. Sapphire crystals offer the best clarity and are often preferred for high-end watches and sports watches due to their durability. However, they are also the most expensive option.
Choosing the Right Watch Crystal
The best watch crystal for you depends on your lifestyle and budget. Here’s a quick guide:
For everyday wear: A mineral crystal is a good balance between scratch resistance and affordability.
For active lifestyles: A sapphire crystal is the best choice for its superior scratch resistance and durability.
For budget-friendly options: An acrylic crystal is suitable if you’re on a tight budget and prioritize affordability over scratch resistance.
Additional Points to Consider
Anti-reflective coating: Many watch crystals, especially sapphire crystals, come with an anti-reflective coating that helps reduce glare and improve readability, especially in bright light.
Crystal shape: Watch crystals come in various shapes, including flat, domed, and boxed. The shape can affect the overall look and style of the watch.
Crystal thickness: Thicker crystals offer more protection but can also make the watch appear bulkier.
Caring for Your Watch Crystal
- Avoid exposing your watch to extreme temperatures, as this can cause the crystal to crack.
- Clean your watch crystal regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- If your watch crystal is scratched or damaged, it’s best to have it replaced by a professional watchmaker.
By understanding the different types of watch crystals and their properties, you can make an informed decision when choosing a watch that meets your needs and preferences.
