Yours appears , to me , to be one of fairly recent manufacture (i.e. 'vintage') .
I believe that the 'Thorens movement' refs to the music box inside your clock , not the clockworks itself .... it should 'play the tune' ("I'm always Chasing Rainbows") at every hour mark .
You do not mention if your item is complete , or if it indeed 'runs' & keeps time ... these considerations will influence its' value .
Knowing how it 'strikes' - as in at what time intervals - and length of time it takes for the clock run-out one 'winding' ( 1 full pull of the weights ) matters too .
Stating the size of the clockface will help , as to knowing the general size of your item .
Cool little clock , Quas .
