According to foreign media reports, Apple Design Director Jony Ive said that Apple Watch contains a very cool silent alarm clock, which can wake users up very quietly. When the user sets the alarm clock, the Apple Watch will not make a sound, but vibrate to remind the user.

It is expected that the vibration warning will be realized by the Tapic Engine in Apple Watch, which is a linear brake and can have different degrees of vibration. In addition, Cook still says that the Apple Watch needs to be recharged once a day, so do you want to take it off at night? It is estimated that the shock will not work if you take it off and charge it.
