Where can I find the sample apps for the Garmin Watch?

 I'm new to Garmin watch app development and I was learning the app development by following the given tutorials in the Garmin website and in their tutorials they keep saying see the sample apps but do not provide any link to them. I need to see some sample apps to understand some concepts (i.e. how different button drawables are made) which are not clearly explained in the tutorials. If anyone knows, kindly provide me with the (link to) sample apps. Thank you.
