How can I get it working again?

I have a T&J Talking watch. PO62523. It has suddenly gone "super fast" with it gaining around 3 hours every 60 minutes.
I took it to my local jeweller/repairer but he said they can never manage to do it and suggests I contact the maker.
Can't seem to find a T & J website. Keep being sent to Amazon. Can you help please?

T&J appear to be one of those "house brands" where a posh label or logo appears on what is basically crap product. Think Qualcast, a once proud braand that is now no more then a label applied to cheap far Eastern procucts andsold exclusive by Argos as an " own brand"
