Apple released watchOS 5.1 today, but after installing the update, it reported that the clock was unavailable and then temporarily removed it from the enabled state. Guilherme Rambo of 9to5Mac met with readers of this issue and several readers MacRumors .
Serious problems with Apple Watch can be more complex to solve than iPhone or other devices. This is because there is no way to connect the device to the computer and reinstall the software yourself. The only means is to contact Apple for service. This issue seems to be confined to the new Apple Watch Series 4, which may cause complaints to affected users.
watchOS 5.1 includes more than 70 new picture emoticons, group FaceTime audio and a new full screen color clock face that comes with iOS 12.1 today. Do not install if you have downloaded updates before you are currently picked up. It is not possible anyway, but it is safer than sorry.
