Seiko uses a special type of mineral crystal called Hardlex in many of its watches. Hardlex is made from ordinary glass that is heat-treated to improve its resistance to scratches and shattering. It also has the added advantage of being treated with inorganic chemicals to make it even more durable.
Although Hardlex is more scratch-resistant than regular mineral crystal, it is not as scratch-resistant as sapphire crystal. For this reason, many people who own Seiko watches with Hardlex crystals replace them with sapphire crystals.
If you are thinking about making this change yourself, this blog post will shed light on why it may be a good option for you.
What Are Sapphire Crystals?
Sapphire crystals are made from a synthetic version of the natural mineral corundum. Corundum is one of the hardest natural minerals, second only to diamonds. This makes it the perfect material for watch crystals because it is extremely scratch-resistant. In addition, sapphire crystals are also resistant to shattering, which makes them great for watches.
What Are the Advantages of Sapphire Crystals?
The main advantage of sapphire crystals is that they are much more scratch-resistant than Hardlex crystals. This means that your watch will look new for much longer. Sapphire crystals are also resistant to breaking, which is an important safety feature. Another advantage of sapphire crystals is that they allow more light to pass through them in comparison to Hardlex crystals. This results in a clearer and brighter display on the watch face.
What Are the Disadvantages of Sapphire Crystals?
The main disadvantage of sapphire crystals is that they are more expensive than Hardlex crystals. In addition, they are also more difficult to replace if they do get scratched or shattered.
Should You Replace Your Hardlex Crystal with a Sapphire Crystal?
The decision of whether or not to replace your Hardlex crystal with a sapphire crystal is a personal one. If you want the best possible scratch-resistance and clarity, then replacing your crystal is a good idea. However, if you are happy with the performance of your Hardlex crystal and do not mind the occasional scratch, then there is no need to make the switch.
Why Switching Your Watch Crystal to Sapphire Is a Good Idea
Sapphire crystal is one of the hardest materials on earth. It is second only to diamond in terms of hardness. This means that it is extremely resistant to scratches and shattering. It is so tough that it is used in the production of bulletproof glass.
Although sapphire crystal is more expensive than Hardlex, the increased durability is well worth the extra cost. Not only will your watch look brand new for much longer, but you will also have the peace of mind of knowing that your watch is better protected against accidental damage.
Is a Sapphire Crystal Worth the Money?
When it comes to deciding whether or not to switch your watch crystal to sapphire, it really comes down to personal preference. If you are someone who is constantly knocking on their watch or are worried about damaging it, then opting for a sapphire crystal is definitely the way to go.
On the other hand, if you are someone who is careful with their belongings and doesn’t mind spending a little extra money on a replacement crystal every few years, then Hardlex may be the better option for you.
