Try to find a pre-owned IWC Ingenieur (3227) or Fliegerchrono (3706) or Aquatimer on the Bay.
None are currently being produced so they might take a bit of doing to find.
They're all relatively large watches so you need at least a med sized wrist.
But they're very impressive and expensive looking watches.
The Ingenieur has it's very own in-house (IWC designed) movement while the Flieger has a highly modified Valjoux 7750 movement.
I've owned both and I can honestly say that IWC's fit and finish is light years ahead of both Rolex and Omega.
(I also owned a Submariner and Bond Seamaster so I know this from first hand experience)
A recommendation from left field is the Grand Seiko or Credor lines from Seiko.
These are not your run of the mill $125 Seikos that you see in the mall.
They make some absolutely beautiful dress watches rivaling the look of the JLC Master line in the classic styling dept. (and I love JLC's)
Their Marine Master is considered one of the absolute best diving watches you can buy.
And all Seikos have their own in-house movements too.
These are only available on line either from Japanese or European companies, so it'll take a bit of searching.
Have fun looking and let us know what you get.
