His approach to printmaking was defined by a soft touch. He translated the oil paintings of Joshua Reynolds and Thomas Gainsborough into monochrome works that retained the feel of the original brushwork. Watson used deep blacks and subtle greys to build volume. In works like 'The Strawberry Girl', he captured the texture of skin and clothing through careful scraping of the copper burr. His prints are known for a lack of harsh outlines.

Modern collectors appreciate the moody, graphic nature of Watson's work. The velvety texture of his mezzotints provides a sense of depth that modern digital prints often lack. These pieces work well in rooms that require a quiet, sophisticated aesthetic. His focus on light and shadow makes his prints compatible with both period-accurate rooms and contemporary minimalist spaces.
