You can never be too rich or………too thin. My 2500 is still in the roster because of its case proportions. Having said that I really love the transparent back and all other things being even would go for transparency over size. As far as movement thickness (admittedly a can of worms and let me state for the record I am a huge Rolex fan even though I don’t own any) I would prefer to own a METAS movement over a non METAS movement thickness be damned. As far as the helium escape valve goes… What are we clinging to? I appreciate it as a whimsical doodad but I could just as easily live without it. I am not in line with the suggestion that they should just scrap it all together, but there’s a part of me that wonders should they amalgamate the 300 and the PO into one watch and have done with it? Frankly, they are almost already there. Which leads me to even deeper questions with regard to OMEGA(ohhh god somebody stop me) I feel like there’s a lot of room to revamp constellation globe master et al.
