I found the new 42mm Explorer II to wear very big! I put it beside the DSSD (43mm) and it looked just as big to me, I then put calipers to it and they read 43mm across the case. So my eyes weren't playing tricks on me, the watch is the same size as the Deep Sea. The EXP II I bought was the 21j superlumed version from Perfect Clones. The gen may be 42mm, but the rep I had was 43mm.
