Camera

Well yes, that is a curious one, since Camera does not show up under "My Watch". However, usually you can still see and access it with the Digital Crown. I do not even know how to remove it actually...

But if it's not there, try this:

1. Open the "Watch" app on iphone and click on Discover
2. Select Explore Watch Apps at the very bottom there
3. Click Search and type in "Camera Remote"
4. Install the "Camera Remote" app by Apple

Hello there! You have to search for "Camera Remote" app by Apple on the App Store of your Apple Watch.

This is a screen shot from my Apple Watch searching "Camera" or "Camera Remote" on the App Store.

It's in the watch app store,just search for "remote" and scroll down the page a bit to see it.
