The 1970s were a revolutionary period for the watch world. With the quartz crisis looming, Swiss manufacturers were forced to adapt to electronic innovation. During this period, IWC launched the "Edison Electronic" series, named after Thomas Edison, the symbol of technology. This watch was a product of IWC's engineering prowess and pursuit of innovation—a milestone that combined mechanical mastery with electronic precision. The "Edison" on the dial wasn't just a model name; it was the brand's outstretched hand toward the future. For collectors, this watch is considered the "missing link in IWC's history"—it combines classic Schaffhausen craftsmanship with the futuristic electronic experiments of the 1970s. Finding a well-preserved Edison Electronic today is rare; it often appears as a minor footnote in documentation of the brand's electronic era.
