When we admire a watch, our eyes are often drawn to the dial, hands, and case. But there is one subtle yet essential element that plays a major role in the protection and clarity of the watch: the glass. Watchmakers carefully select different types of glass for each watch, based on its unique characteristics. In this article, we explore the different types of glass used in watchmaking and their distinctive features.
#### 1. Mineral Glass: The Balance Between Clarity and Strength
Mineral glass, a common choice in watchmaking, is made of tempered glass. While it offers good clarity and scratch resistance, it is not invulnerable to severe impact. It is often the choice for everyday watches that require a balance between functionality and budget. The hardness index (VICKERS) is 700.
#### 2. Sapphire Glass: The Elegance of Resistance
Sapphire crystal, made from synthetic sapphire crystal, is the ultimate in scratch resistance. It is a preferred choice for high-end and luxury watches. Its crystal clarity accentuates the beauty of the dial while providing optimum protection against damage. The hardness index (VICKERS) is 2300. This is the type of glass we use for our Maison MORFIN watches.
#### 3. Plexiglas Glass (Hesalite): Echo of the Past
Plexiglass, or Hesalite, was widely used in antique watches. Although it is less scratch resistant than other materials, it is valued for its light weight and ability to be polished to remove minor marks. It evokes a sense of nostalgia and is sometimes used in vintage watches. The hardness index (VICKERS) is 500.
Ultimately, the choice of glass depends on the style of the watch, its intended use, and individual preferences. Each type of glass has its own advantages and limitations, but they all have one thing in common: they contribute to the overall appearance and functionality of the watch. When choosing a watch, take a moment to appreciate the glass that protects and enhances it, and remember that each choice was carefully made to provide an exceptional watchmaking experience.
