Hi Marcus,
Good question. I have the Plat Langematik w/date and deployant, needless to say it is a magnificent watch.
That being said I dont feel it is an everyday watch for me...more special occasions.
The deployant on the Langematik is a work of art yet, I have never been able to get the watch to fit as comfortably on my wrist as I would like.
I guess I would say the dial on GO is austere and workman like to my eye. Does that make I sense? The Senator is easy to get used to and very comfortable.
Dont ask me to make a choice between the two.
Regards,
Clifford
