I have 3 of the 4 you have mentioned (no 114060). The SD is fatter slightly smaller dial but larger bezel. It has an helium escape valve and goes to deeper depths ( 4000ft compared to the 1000ft submariners). The SD is also heavier.
I believe the 14060m has a modified movement. Someone else can confirm. Also in the later 14060m it had an engraved rehaut and 4 lines on the dial. I think this was 2010 onwards.
