Can't get mirror modifier to work on x and y axes for the same object

Never mind, I figured it out.

I’m attempting to do a blender tutorial I found here: I was able to mirror on the x axis only after making sure my origin was in the middle or center. I can get the Y mirror modifier to work correctly only if I change the origin to the selected (where I deleted the vertices) of the cube. But then my x mirrror modifier object is gone. Can someone tell me how I can get the x and y mirror modifiers to work on the same object for this tutorial? I included three screenshots below to help explain what I mean.

Here the X mirror modifier is working, but the Y mirror is not working right:

Here the Y mirror modifier is working, but the X mirror isn’t.

From the tutorial with subsurf. This is mirrored on the other side of the watch band (not shown in this image.)

Your origin point does not match the location of the origin in the image from the tutorial. In your first image the origin should be just about where the 3d curser is.
