Ceramic has a number of benefits that make it ideal for use as a material in watches, but the most significant is its hardness. Ceramics are extremely hard to scratch, with the commonly-used ZrO2 ceramic rating around 1,200 HV on the Vickers hardness scale. Industry-standard 316L stainless steel, by comparison, comes in at just over a tenth of that. This high level of anti-scratch protection, combined with ceramic’s strong resistance to oxidation, corrosion, and color-fading, means ceramic watches continue to look new for years or even decades after they’re purchased. Ceramic is also considerably lighter than steel, resistant to temperature changes, and is hypoallergenic and gentle on the skin with no metal with which to have an adverse reaction. These features all combine to make ceramic extremely comfortable on the wrist.
