Hardlex vs. sapphire crystals? Tough choice! Hardlex is cheaper and resists impacts, but scratches more. Sapphire is nearly scratch-proof but shatters easier. Go for affordability and impact resistance with Hardlex, or choose scratch-resistant with pricier sapphire.
Introduction
The watch crystal, the transparent window protecting the delicate inner workings of a timepiece, plays a crucial role in both aesthetics and functionality. Two of the most common materials used for watch crystals are Hardlex and Sapphire.
While both offer clarity, choosing between them depends on your lifestyle and priorities. This comprehensive guide delves into the key differences between Hardlex and sapphire crystals, helping you determine the best fit for your watch.
Hardlex Crystal: A Toughened Glass Act
Hardlex is a trademarked name by Seiko for a specially hardened mineral crystal. It’s essentially a type of tempered glass specifically formulated for watch applications. The tempering process involves controlled heating and cooling, enhancing the crystal’s strength and making it more resistant to shattering compared to standard mineral glass.
Key characteristics of Hardlex crystals:
- Durability: More resistant to impacts and shocks compared to standard mineral glass.
- Scratch resistance: Moderately scratch-resistant, but not as scratch-proof as sapphire.
- Clarity: Excellent optical clarity, offering good visibility of the watch face.
- Cost-effective: A more affordable option compared to sapphire crystals.
Sapphire Crystal: The Jewel of Watch Clarity
Sapphire crystal is a synthetically grown material composed of crystallized aluminum oxide (corundum). It’s the second-hardest natural transparent substance after diamond, making it exceptionally resistant to scratches.
Key characteristics of sapphire crystals:
- Scratch resistance: Nearly scratch-proof, offering superior protection against everyday wear and tear.
- Durability: Can withstand some impacts, but more susceptible to shattering compared to Hardlex.
- Clarity: Excellent optical clarity, providing a clear and undistorted view of the watch face.
- Cost: Generally more expensive than Hardlex crystals.
- Anti-reflective coating: Often features an anti-reflective coating (AR coating) for enhanced readability in various lighting conditions.
