Timepieces, specifically mechanical ones, incorporate small gemstones within their intricate movements. These are not primarily for aesthetic enhancement but rather serve a crucial functional purpose. The use of these hard materials at points of friction significantly reduces wear and tear on the delicate metal components.
The inclusion of these elements contributes significantly to the longevity and accuracy of the instrument. Without them, the constant rubbing of metal against metal would lead to rapid degradation, affecting the consistent rate at which the mechanism operates. Historically, natural rubies and sapphires were employed, but synthetic versions are now commonly used due to their consistent quality and lower cost.
