While I do like the looks of the “diet” version, I think the original case is better for the intended version of the watch as a tool. That term is bandied about for expensive luxury watches all the time (e.g., Rolex Subs), but these CWCs were really built as a tool for the MOD. Thus, having a larger case without the bezel hang over is a plus (bezel less likely to be knocked off alignment). Same with the thick crown guards.
I don’t expect my hammers to be pretty, just that they work as intended and don’t break. The original case is just like that.
