i looked into getting a watch for at least a year, like you my first idea was a Tag because thats what my oldman has, but after much thought and doing my homework looking at re-sale value and even watches that increase in value over time, i went for one the Omega seamaster planet ocean.
absolutly love it, they are so well made compared to many other big name watches i have looked at. just go and try one on and you will see what i mean.
