The Hewlett Packard HP01

The Hewlett Packard HP01 is a calculator watch and is considered to be the first #smartwatch. Introduced in 1977 at the height of the LED #wristwatch craze, five models were available, two gold filled models and three stainless models., with prices ranging from $450 to $850. Most of the 28 buttons on the HP-01 are recessed, and are designed to be depressed with a stylus that is stored in the band. The production was stopped by the end of 1979, making them quite rare.

The HP-01 is unique not only as the only Hewlett-Packard watch but it’s also Hewlett-Packard’s first algebraic calculator. It can perform intricate time calculations and also display the day of the week for any date from 1900 to 2099.

I can’t seem to get it to connect to my phone’s bluetooth though.
