You may have a hard time finding one for four grand, though.

Otherwise, if you want gold plated, the Hamilton ThinOMatic might fit the bill. Forty-two mil, auto.

Alternatively, check out Longines, the Master Collection should have something nice for around that price range. If you purchase pre-owned. And I think they too may only be offering rose gold.
