Westerstrand Swiss Clock what type ?

Can anyone recognise this clock by Swiss maker Westerstrand or let me know what type factory , master I cant figure out it takes a large ever ready 9v battery.

 

Westerstrand makes those clocks for industrial use, big factory halls, for church clocks etc. .some models with a master/slave function for additional units.
it has of course nothing to do with SWISS, the face is stolen from the original Swiss railway station clocks. but who cares what those Swedes are doing ?

 

Thanks for the replies very helpful.
