Triathlon Miscommunication

So I think this 5k and running thing that I have started doing has caused some confusion at my house. My watch broke a few weeks ago. I told Artur he had to get me one, since he is the picky fashion one. The one he got me is a Timex Triathlon specific kind. Should I be worried of some hidden expectation/agenda? I have NEVER EVER even MENTIONED the word triathlon in the house. Should I have a talk with him?
