Apple Seeds First Beta of watchOS 5.1.3 to Developers With 'Bug Fixes and Improvements'

Apple today seeded the first beta of an upcoming watchOS 5.1.3 update to developers, four days after releasing the watchOS 5.1.2 update with new complications for the Infograph face and ECG functionality for Apple Watch Series 4 owners.

Apple's release notes state that watchOS 5.1.3 "contains bug fixes and improvements," so this appears to be a minor update.

Once the proper configuration profile has been installed from the Apple Developer Center, the new watchOS beta can be downloaded through the dedicated Apple Watch app on the iPhone by going to General --> Software update.

To install the update, the Apple Watch needs to have at least 50 percent battery, it must be placed on the charger, and it has to be in range of the iPhone.

I literally have been updating an Apple Watch so when my fiancé opens it she does not have to go through hours worth of software updates. I just wrapped it and put it under the tree and now it looks like there might be a software update. Grrr.

Can anyone confirm that ECG does not disappear after updating to 5.1.3?
It’s based on approval, not os version, but no, not in UK.
