Apple Seeds Second Beta of watchOS 5.1.2 to Developers

Apple today seeded the second beta of an upcoming watchOS 5.1.2 update to developers, one week after seeding the first beta and a little over a week after releasing watchOS 5.1.1, an updated version of watchOS 5.1 that addressed a bug causing some Apple Watch Series 4 models to be bricked after installing the software.

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.

As was discovered in the first beta, the watchOS 5.1.2 update introduces new complications for the two Infograph watch faces on the Apple Watch Series 4. New complications include Mail, Messages, Home, Maps, Apple News, Find My Friends, Phone, and Remote.

watchOS 5.1.2 also introduces a new toggle in Control Center for turning the Walkie-Talkie feature on and off.

The previous watchOS 5.1 and watchOS 5.1 updates introduced support for Group FaceTime in an audio-only capacity, brought new emoji characters, and included a new full-screen "Color" watch face option for the Apple Watch Series 4 models.

It does display the unread number, it just takes a minute to show it. Don’t know if this new beta improves that or not or not.
Admit it, you just posted this to show off your movement goal was smashed. Great job man ;)

messages is a welcomed complication. I'd really love a seconds option on the digital time displays. Also, would be great if we could have the sunset complication on the digital time info face. Only on the analog infograph right now.

As for walkie talkie, it was an interesting gimmick, but I don't think I'll ever use it again. If you're busy and the message comes through, you miss it. I don't see a replay button. Seems we'd be better served with just a voice message back and forth. But, that might just be me.

I thought I was the only one waiting for sunrise/sunset complication. I’ve gotten too used to having it on the previous watches.

Wow, this is actually going to immensely improve my Apple Watch experience. I’ve been avoiding the new faces because I don’t have a Messages complication. Unfortunately it doesn’t look like it displays the number of unread, but I’ll take what I can get from Apple on the software side.
