Time in cinema recorded as sleep

Yesterday morning I bought a TomTom Runner 3. It worked perfectly in the gym; unlike with my previous sports watch I get accurate heart rate readings. But yesterday night I went to the cinema. And now I notice the watch recorded the time in the cinema as sleep. Start and end times match almost perfectly with the running time of the film. And I can assure you: I did not fall asleep during the film. In fact I really liked it (it was The Square.) Is this something that will happen every time I watch a movie, tv or read a book?

    Sleep tracking is based on lack of movement. So unless you start moving your arms more while watching the movie, it will indeed register as sleep time.

    Wow, if it works like that, it's useless. I thought it's based on 24 heart rate monitoring.. at least might be both - you're not moving for a while but your heart rate looks like you're doing something - not sleeping; Often heart rate monitor is not accurate, but then if it's under 50bpm but it looks like your in move - not sleeping.
    And what if you turn over to the other side while sleeping? You moved - not sleeping? :/
