Omega PO 8500 would be my choice in your price range if I only had one watch. But you said no Omega, so second would be an IWC Aquatimer 2000.
Maybe consider 2 watches for that price? I have been rotating a PO 2500 and Sinn U1 SDR and my Breitlings have been collecting dust. You could pick them up for less than $5000
