Historical Evolution of Sapphire Watches

Early Uses in Watchmaking

Sapphire has been part of watchmaking since the early 1900s. The first synthetic sapphires were created by French chemist Auguste Verneuil in 1902. This innovation allowed watchmakers to replace expensive natural jewels with synthetic ones, making watches more affordable and durable.

Technological Advancements

By the 1930s, sapphire crystals began appearing in watches. The Jaeger-LeCoultre Reverso is often credited as the first watch to feature a sapphire crystal. In the 1950s, brands like Omega started using sapphire crystals in some of their models. This marked a significant shift in watch design, as sapphire became a standard feature in many luxury watches.

Modern Applications

Today, sapphire is widely used in various types of watches, including luxury watches for men. Its durability and scratch resistance make it a preferred choice for both casual and high-end timepieces. Many brands now offer watches with sapphire crystals as a standard feature, ensuring that they can withstand daily wear and tear.

Sapphire has transformed the watch industry, providing a blend of elegance and strength that appeals to many watch enthusiasts.

Manufacturing Process of Sapphire Crystals

Melting and Crystallization

Sapphire crystals are created by melting pure aluminum oxide at very high temperatures, typically between 2000℃ and 2200℃. This process is done in a furnace, where the material is heated until it melts, then cooled to form crystals. The result is a solid mass of sapphire that can be cut into smaller pieces.

Cutting and Polishing

Once the sapphire has crystallized, it is cut into small disks using a diamond-coated saw. This step is crucial because it shapes the sapphire into the desired form for watch crystals. After cutting, the disks are polished to achieve a smooth and clear surface, which is essential for visibility.

Anti-Reflective Coating

To enhance the clarity of the sapphire, an anti-reflective coating is often applied. This coating helps reduce glare, making it easier to read the watch dial. The coating is typically applied to the inside of the crystal to protect it from scratches.

The manufacturing of sapphire crystals is a time-consuming and costly process, but it results in a product that is highly valued for its durability and clarity.
