Description

The donor describes this object as follows:
"During the early 1970s, solid state watch modules began to appear, as shown in this array. Such modules were initially directed at the emerging LED watch market, which used single chips to present each of the 4-digit displays. As time progressed however, the industry switched away from LED watches in the mid-1970s, with the introduction of liquid crystal displays, as shown in item #61"
