Which component uses the Apple Watch Photos app?

Question

I want to create an application for viewing photos for an Apple watch with a look similar to the image of the apple Photoshop application.

Here is a demonstration of what I need. I want to enlarge the image using the digital crown. Also has a choice.

However, with current examples and application demos there, I'm not sure what components of this view are made.

If someone knows a solution to this kind of implementation, please help me with it.

Sample code / code snippet / tutorial will be highly appreciated
