What's it worth? Appraisal of Semca vintage alarm clock

Mike asks:

This has been in my family longer then me.  I got it from my great aunt and uncle.  It runs and the alarm works.  It is marked Phinney-Walker Alarm Germany on the front.  On the back it looks like it is marked SEMCA CLOCK CO INC GERMANY
