Can anyone please tell me something about this

Hello everyone I recently picked this up for £1 at a charity shop and I am wondering if it's authentic I don't know much about watches so I thought I'd ask people here for help, I went to a few jewellery shops and they all said it looks fake but I thought I'd double check on here as from the inside of the watch it looks more promising to me nevertheless I'm almost certain it's a fake let me know what you think please
PS sorry for the bad photos it's the best I could do.

Hi Scott
Sorry to tell you but it's 100% fake
TAG Heuer watches are made in Switzerland not Hong Kong

Sorry to say you overpaid.
