The 743 calories is a predicted value of what you have been burning since midnight.
The device gives a readout for the full day (well full day up to the time you check it) even if you have not had it on the entire time. It gives an estimate for the time periods that you do not have it. So when you first receive the device ... and have to wait impatiently for the thing to charge ... it does not start counting from the moment you start wearing it, but gives a predicted value for up to that point. The estimate is based on your stats at first (because it doesn't have any other data yet) but over time it will base off-body estimates on the data it receives from you.
If you still think the number is too high, like maybe it estimated a more active morning than you actually had, go to the website and look at your calorie graph (I assume you have already seen it with any syncing/registering the device). If you have synced it, then there should be a link in the err... top left corner of the graph that says "off body." If you click on it, it will take you to options of what you did during that time period. This is also helpful if you wanted credit for something you did while you were charging or otherwise not wearing it (such as swimming).
