Maybe the lugs are included in the official specs' height/thickness. If you put it flat on the table the backside doesnt touch the surface because the lugs protrude a bit - maybe to protect the sensor from scratching. I ignored the lugs though as they're wrapping around my wrist and don't add to the thickness. Or maybe i measure again to be sure.
