Question: Story about Big-Brother-like society where everybody wears a controlling wristwatch
Answer: ''The Creature from Cleveland Depths'' was a short story by Fritz Leiber written in 1962. As noted in my comment above, an engineer devises a little clockwork/tape-based thing where a man can make notes and reminders, and the device would give the wearer a slight shock, a "tickle" when the time hit, reminding him to check his appointments. His friend, a marketer, stole the idea (which he was noted as doing often, something the protagonist cheerfully grumbled about) and released it, claiming his company had been working on it all the time. As time went on, the tickler was improved to also automatically remind a person to do routine chores, and to even inject drugs to help make them happier. By the end of the story, the engineer, who has refused the tickler, realizes that the ticklers have taken over.

One of the other odd details that stuck in my mind was that the marketing friend drops off a case of lifelike masks for the engineer, prior products of the company, and he and his wife have a brief bout of fun while she's wearing the face of a prominent actress.
