A Guide On Sapphire Crystals on Watches

Sapphire crystal is a term you've undoubtedly heard of if you're familiar with watch jargon. The watch's lens, also referred to as the "crystal" or "glass," is the one that experiences the most wear and tear out of all the parts. The lens, which covers the dial as a protective layer, is prone to scratches and other damage. As a result, watch companies have always experimented with various materials for watch lens construction. Numerous materials, including plexiglass, acrylic, mineral crystal, sapphire crystal, and hesalite crystal, can be used to make the lens. Today, we'll talk about one of the most expensive and sought-after materials used in watchmaking - sapphire crystal. Read on to discover why this watch component is so fantastic!

What is a sapphire crystal?

Sapphire crystal isn't actually a type of glass. It is actually pure aluminum oxide that has undergone extremely high temperatures during the crystallization process. The outcome is sapphire crystal, an extraordinarily durable and resilient substance. A diamond is rated ten on the Mohs scale, but a sapphire crystal is rated nine! Because of its exceptional scratch resistance, it's a great material to use for watch lenses. This transparent material, highly esteemed in the industry, transformed the entire watchmaking process. Its strength is comparable to natural sapphire gemstones in terms of hardness. 

What is the process of making sapphire crystals?

As was previously noted, pure aluminum oxide crystallizes when it is heated to extremely high temperatures, producing sapphire crystal. The substance creates masses after it crystallizes. Manufacturers slice tiny pieces out of these bulk with specialized diamond-covered cutting tools. Typically, the cut parts take the shape of disks, which are subsequently polished and honed into the sapphire crystals we see on watches.

Why are sapphire crystals so expensive?

The process of creating sapphire crystals is typically costly. Due to the high cost of the tools required to cut and shape the crystal, few manufacturers will employ them. The procedure is also labor-intensive, drawn out, and time-consuming. Because of this, sapphire crystal watches, in addition to being extremely high-quality, exude prestige and elegance. Its rarity and value are increased by the fact that it is among the hardest materials on Earth. Since sapphire crystals are practically impervious to scratches, watches featuring such lenses are made to last a lifetime!

Sapphire Crystal vs. Mineral Crystal

Mineral crystal is still far less expensive than sapphire crystal, even though it is slightly more expensive than plastic or acrylic substitutes. Its greater scratch resistance makes it a better option than acrylic or plastic lenses, although sapphire crystal is truly not comparable. Nevertheless, for those looking for a respectable mid-range watch, it's an affordable choice. However, if you're willing to shell out a little more cash and want a watch that will last, going with a sapphire crystal watch is highly recommended. In the long term, its lifespan will pay you tenfold. Sapphire crystal timepieces are unquestionably the greatest choice if you're searching for sturdiness and distinction.
