I am looking for micro/nano servo recommendations. I am working on a clock so I need the precision. Looks like every continuous micro servo I look at is for wheels so the precision/accuracy is not an issue. Alternatively, if they can turn 1 rotation per hour Id also be happy. Any recommendation helps!
Continuous rotation servos have NO positional control. They just go round slower or faster. For a clock you should probably be looking at stepper motors. A search on "arduino stepper clock" should find you some ideas.
