In Pictures: Groovy 1970s consumer tech

Watches

Electronic digital wristwatches first emerged in 1972 priced at $2100 (the equivalent of $11,387 today), but by the end of the decade, they would regularly retail for under $10. The first watch, the Hamilton Pulsar P2, shipped in an 18K gold frame with a battery-hungry red LED display that became visible only when you pushed a button. By 1976, Texas Instruments sold LED watches with plastic bands for $20 apiece. LCD watches, with their far more power-efficient displays, overtook LED models in popularity by the end of the decade. The cheapest LCD watch on this page (#3) from a 1977 Sears catalog sold for $70.
