Bug report logging inside watch

Hi guys,

I have an app that is running fine in the simulator on the PC, but when I run it  on the watch, it crashes on the main view page, after a random number of seconds, where seconds can be any random number, Ive seen 2 minutes or 10 seconds.

It seems to be something to do with either the calculations or GPS info

Is there a way I can get some kind of crash log back from the watch?  how do I do that?
