If you can believe it, there is a lot of debate about the different kinds of materials used for safeguarding the face of a watch. There are numerous varieties of glass, each with its own unique set of properties. If you are passionate about watches, you may find this topic interesting to you. The question of whether or not the use of various materials makes a difference will be addressed in this article.
This guide can assist you in deciding whether or not to purchase a watch if you have been on the fence about doing so. You’ve come to the right place if you’re not entirely sure what a sapphire crystal is or if you’ve heard of something called Hardlex, but you’re not entirely sure what it refers to.
Watch glass is a piece of transparent material that covers the dial of a watch and can be round or square depending on the form of the face of the watch. You probably already know this. It is there to safeguard it from any impact that may be received. It is also possible to utilize it as a magnifier for a certain part of the device, such as the day/date window. Cyclops lenses are what you’d call any of these extremely minute magnifying sections that you might come upon. Your first interesting tidbit!
You now have the necessary knowledge to move on to the next step, which is to understand what a watch glass is and its function. Now that we’ve got that out of the way let’s get into the specifics of the various watch glasses. The items on this list are ordered from the most delicate to the toughest.
When compared to the other materials used to make watch glass, acrylic is the most delicate. Acrylic being delicate is due to the fact that it is, in fact, plastic. Acrylic is not the actual glass. It has a low overall strength because of the fact that it can be produced at a low cost.
Acrylic glass is the material that can be found most frequently on cheaper timepieces. This material is frequently used by lower-end watch brands such as Lorus and Timex for their sub-$100 timepieces.
Acrylic could take you by surprise if you find it on a high-end clock, but it does sometimes appear there. For instance, Junghans uses a substance known as “plexiglass,” which is really just a sort of acrylic with a fancier name. On the specification, words and phrases such as “perspex,” “acrylic,” and “lucite” can be found. In such a case, you are now aware of what it is.
The fact that acrylic is a lightweight material is not a negative trait of the material. Do not discount the possibility of purchasing a watch made of acrylic glass if you are interested in purchasing a watch that is either extremely thin or completely weightless.
It is common for it to be found on children’s watches, not because of its longevity but because of the high probability that it will need to be replaced. As a result, the expense of doing so will not cause a parent’s budget to become unmanageable.
Advantages include the fact that it is inexpensive to produce, simple to replace in a cost-efficient manner, and does not add unnecessary weight to the watch. In addition to that, scratches are simple to remove.
Cons: It appears to be more expensive than it actually is, and it is flimsy.
Mineral crystal is the type of glass that may be found on most watches. That is if you want to aim for a price tag that is somewhere in the middle. It is fabricated with tempered glass, which is the industry standard and is derived from silica. Because of this, the mineral crystal is scratch-resistant to a greater degree. The fact that it can be produced with a low overall cost accounts for its prevalence in most situations. However, it cannot be guaranteed to be scratch-proof in any way. After a period of time, it will inevitably acquire a few marks here and there. You will need to get it serviced or send it back to the watchmaker to remedy this problem. The watchmaker will be able to examine it and let you know if it is more cost-effective to buff it or to replace it.
Some watches out there have mineral crystals, and some of those watches have a coating that makes them anti-reflective. It is also referred to as AR, which stands for anti-glare.
Anti-reflective coating is typically applied to sports watches to improve their readability in low-light environments. It can provide a sharper image of the face, which results in less strain for the person who is wearing it. It also lends the whole appearance a more polished finish, making it appear to be of higher quality and cost.
Advantages include superior protection against scratches compared to acrylic, the ability to be further improved by AR, and an overall more premium appearance.
The disadvantages include the fact that it is not completely scratch-proof, that it is more difficult to remove scratches, and that it is more expensive.
Crystallized Sapphire is the finest that can be offered to you. Suppose the dial of the wristwatch you are considering purchasing is protected by sapphire crystal. In that case, you can be confident that you will purchase the highest quality watch glass currently available to you.
It’s possible that you’ve already guessed, but the material is sapphire. Warning: this is a spoiler, although it turns out to be fake rather than real. The remarkable scratch resistance and overall durability of sapphire make it a desirable gemstone. They look fantastic, too. To leave a mark on it would require something as precious as a diamond.
It’s possible that you’re mulling over the fact that you were under the impression that sapphires were blue. You have not made a mistake. Indeed, they do. Did you know that they can also be colored red, green, yellow, or purple?
The color can be affected by impurities such as titanium (another unexpected element), iron, copper, or chromium. A hue is produced by these and other components as well. Genuine sapphires that are eye-clean are quite uncommon. Therefore seizing the opportunity to acquire one would be wise. Because of this, it is much simpler to create a synthetic equivalent.
A chemist in France is responsible for its creation. He used aluminum oxide as his raw material and then subjected it to high heat and pressure in order to create enormous sheets of the substance. The powder changed into crystals and performed some additional magical work to eliminate any internal stresses, allowing it to be as strong as it possibly could be. Following this step, the material is flattened into a sheet, at which point it is transformed into sapphire crystal glass, which is then ready to be shaped for use in watches.
Be advised that despite its incredible resistance to scratches, it is not indestructible and can still crack or shatter if subjected to a sufficiently severe impact.
Advantages: The most beautiful scratch-resistant material that is currently available, and it performs exceptionally well.
There are a number of drawbacks, the most notable of which are its high price and the possibility that it will crack.
