Forerunner 945 LTE buttons feel flaky?

I have a new Forerunner 945 LTE - arrived today. I'm a bit surprised that the feel of the buttons isn't a bit more solid, crisp, and well-defined. It's almost as if there's a sort of multi-step travel in and out as you push and release them. Not the kind of tactility that inspires a lot of confidence, either in the use or in the quality of the watch. Would love to know if they are all like this and this is just how the model is designed, or if I have a lemon and should return it...
