Small list of fixes from watchOS 3’s beta 4 release notes:

Emergency SOS If the system volume is turned all the way down when you trigger Emergency SOS, alert tones are heard. Xcode • Complication bundles now appear in the Face Gallery in iOS Simulator. • Time travel is now useable in watchOS Simulator

In today’s beta update, Apple has updated and clarified some of the experience around Emergency SOS as well:

When you press and hold the side button, you can automatically call emergency services. To cancel or disconnect the call, press firmly on the display and tap Cancel. After a call with emergency services is complete, Apple Watch can notify your emergency contacts via Messages that you have contacted emergency services, and will share your location. If you don’t want your emergency contacts notified, you can tap Cancel. To configure Emergency SOS, go to the Watch app on your iPhone, then General > Emergency SOS. Here you can disable Auto Call, add SOS Contacts, and learn more about SOS.
