The present disclosure discloses a smart watch, an operation control method and an apparatus therefor, the smart watch comprising a watch body and a watchband, wherein the watch body comprises a display screen and a system board, the system board comprising at least a microprocessor, a memory and a communication module. The watchband is configured to fix the watch body on a user's wrist. A biosensor is integrated on the surface of the wristband on the side adjacent to the user's wrist. As the watchband can contact directly with wrist side nerves, more accurate test results can be obtained, and the operational complexity is simplified. At the same time, by canceling the bezel design and performing a corresponding operation according to a touch operation detected in a functional region, the size of the smart watch is reduced and the comfort and flexibility during wearing is improved.
