Both the GS and the Omega are great options !!! i would also look at Baume & Mercier Clifton Baumatic. More of a dress watch but with an in house cosc certified mechanism with 5 days of power reserve.
To be honest i think i would go for the GS since i really love that watch !!! But i dont think you can go wrong with any of these choices.
I just hope you are trolling......
