The Swatch Talk watch had a built-in what?

The Swatch Talk watch had a built-in telephone. It combined a wristwatch with a miniature cordless-phone handset, using a speaker and microphone built into the watch body so the wearer could make or receive calls.

Swatch Talk appeared during the late-1990s enthusiasm for shrinking everyday electronics into wearable gadgets. Contemporary descriptions presented it as a fashionable Swiss watch that also functioned as a telephone, rather than as a conventional watch with a messaging accessory. Its unusual form made it an early example of wearable communications technology.

The model is sometimes confused with other telecommunications-themed Swatch products. Swatch also sold pager-related watches, including Swatch The Beep, but a pager only received messages and could not carry a voice conversation. A radio would receive broadcasts, and a camera would capture images; neither describes the defining built-in feature of Swatch Talk.
