1) 38mm includes a small and medium band, whilst the 42 mm comes with a large and medium band. 2) The resolution on 42mm is nominally better and the text is bigger. 3) The batter on the 42mm is supposedly 30% bigger, providing slightly longer battery life. 4) The 42mm is slightly thicker than the 38mm.
