IMHO, 10k is neither here nor there. Too much for a decent watch but not enough for a really nice one either.
If you're aiming for a proper luxury brand in the future, for now best to just get a nice Seiko automatic ie. Divers, Presage etc. for less than 2k and put the balance 8k in the kitty for something really nice in the future.
But if you know 10k is all you'll ever want to spend on a watch, go with one that you like looking at & messing with everyday, regardless of future residual value or investment etc etc.
