j.hoI can't say officially, but I did some investigation on the movement: http://www.longain.com/en/parts/detail.php?catId=30&item=1
I believe this is the variation - and therefore not the 'sweep alarm movement'. But I'm no expert - I just lined up the turn knobs on the back with the various Wellgain SAL 368 Quartz Movement variants.
j.hoOn mine - received yesterday - it is a sweep hand, with completely smooth rotation (no jerks at each second position), and does NOT stop at 59 seconds.
