Lots of great info on WUS and a marketplace that you may potentially score the watch you decide to purchase and save some bucks.
My collection includes Seiko (Tuna, all around perfect watch), Deep Blue (Daynight Recon Tritium T-100 , what a lume!), Halios (1000M Blue Puck, this sees a lot of wrist time), Omega (Speedmaster 3572.50, my grail watch), and a few others that I just can't seem to part with...and there are a few on the desired list, one of which is an IWC but I doubt that I will buy it for a while.
I see lots of connection between well-made watches and our beloved and well-engineered Porsches.
Good luck on your search!
