LIBERTO DENIM Advertising Time Zone Clocks

The other day I bought this clock - just because it took my fancy.
The case measures 16+1/2ins x 10+3/4ins x 2ins.
The bank of clocks have come loose from their fixings and slide about inside the case. The TOULOUSE clock is working, but the American ones are not.
The advert on the outside is repeated inside the casing.
I have searched Google but can't find anything like this clock. Does it have a value of any sort? Is it worth paying for it to be repaired professionally or do I let my hubby loose on it?
Thanks for any advise
