Update, basically there isn't one
I emailed the company on Monday with photo's of the damage and my unhappyness and received a reply on Tues morning to say could I send some images that I had already sent to their customer services on Monday

so sent the email again on Tuesday Morning.
Oddly I received an email below late on Monday night from them so I responded back again, again with photo's and have received no response back to any of my emails,
Dear Tim,
I hope this email finds you well.
I would like to take this opportunity to personally thank you for choosing Luxury Watch Repairs.
I am pleased to see that you have received your watch back and am following up to ensure you are satisfied with the work carried out and service received?
I look forward to hearing from you and remain at your disposal if I can be of any assistance in the meantime.
With best wishes,
David
Customer service manager
Unsure where I stand now or what I can do, I have a feeling they have washed their hands of it, hence no reply back. I don't know whether to just suck it up and put it down to experience as I don't really wish to send the watch back to them now anyways, I don't trust them to carry out any further work.
All I can say is avoid ths company going by my experience with them.

I understand from some watch forums their Trust Pilot reviews on their website are invited reviews by the company hence them all being glowing, however further Googling reveals alot of unhappy customers which in hindsight I wished I had come across before using them.
Tim.
