So to close off this thread, yesterday I took my son shopping to look at some watches, we had already discussed a number of options and models he liked, but he eventually went for the Tudor Heritage Blay Bay with the black aged strap, which we collect in a couple of weeks time.
He is over the moon and I am pleased that I could help him get his first decent watch. You never know, maybe it will be the first of many throughout his life just as it was for his old man at his age
I also just wanted to say many thanks again for all the advice, recommendations and input from everyone, it was really much appreciated.
Keep safe and stay well
