The watchOS 5.1.3 update brings bug fixes to the Apple Watch shortly after the watchOS 5.1.2 update added the ECG support and a collection of other fixes. With any watchOS update there are good reasons to upgrade right away, but there are also some reasons not to upgrade on day one.
In November after watchOS 5.1 broke some Apple Watch models and Apple was forced to push out watchOS 5.1.1, which is why the Apple Watch update numbers were slightly off from the iPhone and iPad. It’s all synced up again now with iOS 12.1.3 and watchOS 5.1.3.
ECG mode for the Apple Watch 4 was a major feature in the last update, but this one focuses on bug fixes. This update is coming to all models on watchOS 5, but the ECG feature is exclusive to the Apple Watch 4. There is an irregular heartbeat detection feature coming to the Apple Watch Series 1 and up.
Unlike the iOS 12.1.3 update, you cannot go back to watchOS 4 or watchOS 5 if you don’t like this update. Apple’s watchOS 5.1.3 update arrived today around 10 AM Pacific, 1 PM Eastern.
It will take a while for you to install the watchOS 5.1.3 update to your Apple Watch, but not as long as the main watchOS 5 update. You need to install the iOS 12.1.3 update before you install this, so you’ll want to read this post about the reasons to install iOS 12.1.3, and the reasons not to before you make that jump.
Most of the reasons to install watchOS 5 and watchOS 5.1.3 are about the exciting new Apple Watch features that add to the long list of things the Apple Watch can do. There are also performance improvements and other upgrades. Keep in mind that you may run into watchOS 5 problems and you will need to wait for another update since there is no downgrade option.
There are loads of reasons to install watchOS 5 or watchOS 5.1.3 on your watch today, but there are also several very important reasons not to install this update yet.
