Early gadget watches have appeared in film and TV long before real-life examples existed. Since 1946 comic strip detective Dick Tracy communicated with police HQ through his “2-Way Wrist Radio” watch (later upgraded to TV)
And of course James Bond often sported a nifty gadget watch in his films, the buzz saw watch from “Live and Let Die” is pictured below left.
The combined advances in integrated circuit development and LED display technology led to the first affordable portable electronic calculators in the early 1970’s which in turn led to the first gadget watches; calculator watches, the first one appearing in 1975.
Since then they have become more and more sophisticated leading to more advanced gadget timepieces such as the first pda watch released by fossil in 2002.
