Watch Rejecting an app to install from iPhone watch app

I am using Mac visual studio Xamarin to develop my application. I have two application project (myapp-x and myapp-y) with me, both the application have watch application as well. I can install myapp-x in my watch from watch app in iPhone it get install and I can use it freely but I am trying to install myapp-y, it showing up installing from watch app but after the installing finish watch doesn't show up the application and watch app is showing to install the app again. I tried to install it again but it seems watch is rejecting the application to install for myapp-y where as myapp-x works completely fine.
