Apologies, I'm a little late to the discussion (hate it when work gets in the way of "designing watches") ;-)
I was surprised how the naming of the watch turned out, given that we had all these great alternatives and prefer the dial showing 300 m ~ 1,000 ft rather than Project 300.
In addition, I'm not too hot on the circle Y - as some already pointed out, it's either that or MKII and since the brand name is still MKII ...... Which leads me to vote for dial B.
Still torn between the date and no-date version. I like the symmetry of the no-date version better, but then, giving up on the date altogether .... don't know. And the details pointed out on the "rounded" date window are just beautiful - it's indeed the difference between a cheap looking homage and a true one.
PS - Menno: Watchco is having a big sale on eBay. Still bummed that I missed out on their final SM300's. They sold a proverbial bunch - their last ones. Then a week ago, there were 6 more last ones (missed those too as I was travelling on business)
