As for the design of the Simplicity I am one of the few who would prefer that watch in its 34 mm case. It is the one I came close to ordering.
I have seen the Gauthier in person. Unfortunately for it, it shared the table with a Roger Smith Series Two.
My problem with the Patek is that the seconds subdial is too close to the center. I know this is a function of their using the small caliber 215 PS in a large case, but I just don't like it. I'd rather just live with a small PP watch that looks better.
I have yet to see a Moser watch in person. I like what I have seen in pictures.
