the Milspec 1 IS my favorite watch, and without a doubt, it is the iconic fifty fathoms,
However, as you say, there is also something truely beautiful about the very simple rotomatic incabloc dial that has something...
its a bit like the early Submariner, versus the early Explorers. Its nice to have the icon, but the predecessors in the chain of events that led to it also hold the many of the key incrediants that led to the icon!
Of these two, I go for the rotomatic. (and it's purely because I don't have one!! LOL! )
