A gold filled item has gold on the outside, and is filled with a base metal. Gold is recovered from dust (jewelers sweep the dust from their work areas where they file and shape gold) and from scrap jewelry, plated items (electronics connectors) etc. The metals are dissolved in strong acids, and then the pure gold is removed from the liquid by an electrolytic process. A DC current is passed through the liquid, and the metallic gold concentrates at one conductor, This is pure 24K gold, and must be alloyed with other metals to be usable in jewelry. 24K is too soft for most jewelry.

The thickness of gold on a gold-filled watch varies, including on the same watch, as a gold-filled finish can vary in thickness. But generally, a gold-filled finish will be about 20-40 microns thick. A 20 micron gold-plate finish is a bit thinner than most filled-gold finishes but is more uniform. A 20 micron gold-plate finish will wear a long time and compares well with a gold-filled finish.
