Actually most watch dont retain value...
As mentioned, you should buy what you like having on your wrist. If its for everyday use, your choice seems good enough, and with your budget, that's a lot that you can consider. Tag, ML, Ball, Longines, Hamilton, Laco, Archimede, Stowa all have potential to be a good watch.
So the first advise is to: "take your time to consider"
One of the advice you will hear the most is "add a bit more and buy a pre owned sub", its your choice, but for a first watch, i would say, but something new you like within your budget. The best start is to have something decent on your wrist but aiming for grail in your mind and working towards it.
PS: Tag Calibre 5 seems to be good for a first watch
