I have this view on watches. You either go Omega/Tudor/Rolex upwards, or you just get a Seiko.
I would not be spending £1000 on a mid tear watch, often some of these mid tears are worse quality than a Seiko at far less money.
What I would do is save money and get a second hand Omega Seamaster, or Omega Man on Moon, Tudor Black bay second hand, Rolex 40mm Explorer 2 second hand. All these are investments that you can wear for you entire life and value will only go north.
Christopher Ward C60 is a nice automatic dive watch at this price point:

I'm a big fan of the Seiko Kinetic watches. Nice movement and great quality.
Unfortunately someone half-inched my current Kinetic at the gym, so I've fallen back to my Tissot and Invicta watches.
