What should my next watch be?

So, I have a 6 watch collection consisting of BB 41, Panerai PAM214, Squale Matic, GS Shunbun, Omega speedie and Laco Paderborn Flieger.

I'm torn between getting a GMT (Tudor FXD GMT), Pelagos LHD, or an IWC Pilot Chrono 41. Though they are all very different watches, I'm after a tool, utilitarian looking watch.

Any thoughts or other suggestions given my current collection?
