Apple has released watchOS 5.2 beta 2, for Apple Watch Series 1 and above. The update is not accompanied with any release notes so it is expected that the changes are bug fixes or under-the-hood updates aimed at developers.
The last operating system update for Apple Watch was watchOS 5.1.3 which shipped with minor bug fixes and improvements. Earlier, Apple had released ECG app and Irregular Rhythm Notification with watchOS 5.1.2. ECG works only with Apple Watch Series 4 while Irregular Rhythm Notification works with Apple Watch Series 1 and above.
Installing watchOS 5.2 beta
To install watchOS 5.2 beta 2, you must be a registered Apple Developer Center member. This will allow you to download the beta profile, which will enable your Watch to receive watchOS beta updates. If you already have the beta profile installed, go to General > Software Update in the Watch app on your iPhone to download the new release.
Apple does not have a public beta testing program for watchOS due to the reason that there is no way to restore an Apple Watch at home. If you are using a developer beta on your Apple Watch and it somehow gets bricked due to faulty updates, it has to be taken to an Apple Store. Unlike iPhone and iPad, there is no restore mode on Apple Watch. So make sure you know the risks before you attempt to install a test build on your Watch.

Apple’s release notes do not mention any new feature or change except for this known issue:

We will update this post if we find any new noticeable user-facing features.
