Embodiments of this application provide a communication signal detection method. The method is implemented on a terminal device. The terminal device detects a trigger event; performs self-detection on the terminal based on the trigger event, where the self-detection is detecting a status of a wireless signal of the terminal device; and prompts reminder information when determining, based on the self-detection, that the wireless signal is abnormal. In technical solutions provided in the embodiments of this application, a self-detection capability and self-detection efficiency of the terminal device are improved, and a user operation is reduced, thereby improving user experience.

One aspect of the invention relates to a horological assembly (2000) including a watch (1000) and an adjustment tool (200) for driving, without direct contact, a first mobile (1) internal to the watch (1000) throughout its case, for adjustment and/or recharging, the adjustment tool (200) including first magnetic areas (210) cooperating in attraction or repulsion with the first mobile (1) which is pivotably and axially movable about a first axis (D1) against an elastic return means (5) fastened to the case (10), between an active position in which the adjustment tool (200) draws the first mobile (1) towards an end-of-travel surface (6) in an engaged position with a second mobile (7) inside the case (10), and an inactive position in the absence of the adjustment tool (200) and in which the elastic return means (5) keeps the first mobile (1) disengaged from the second mobile (7).
