Giant Chronograph (Nov, 1949)

Giant Chronograph
watch was built at the Western Pennsylvania Horological Institute to teach students how to repair this type of timepiece. It’s 23 inches in diameter and the entire movement weighs about 60 pounds. The difference between this model and its tiny counterpart is that the big watch has its transparent face on the back.
