In 1972, Intel entered the business of wearable tech with its acquisition of digital watchmaker Microma. They exited the business in 1977 after realizing marketing a consumer product is completely different from the chip business and requires different skills and staffing.
Microma watches were finicky, especially the display, and return rates were over 25%. Plus the batteries did not last long and competition heated up with Seika, Citizen, and General Time Corporation.
