Asterism is a watch term referring to a special feature that appears on certain watches. It refers to the effect of light reflecting off the facets of a diamond or other gemstone, creating a star-like pattern. This effect is caused by the cutting of the gem, and can be seen in watches with gemstones set into the dial or bezel. Asterism watches are often considered a sign of luxury and style, and many collectors seek out examples of these watches.
