I have a Bernina and attend most of the Bernina club meeting my LQS holds and I've never heard of "hours" the machine ran, but I have heard of the number of stitches. That is something the service tech would have to look up for you. My Bernina counts the stitches but it doesn't tell me how many - it just shows me the icon saying it needs service. If you own a Bernina or are thinking of buying one, ask them at the Bernina store.
