OP,
My wrist is just under 7"...
No to the DSSD (just felt imbalanced imho- bracelet too skinny)
Yes to the classic Seadweller.
Yes to the JLC Navy Seal... except one thing regarding the crown- it does stick out quite a bit. Depending on how you wear watches, that extended crown can poke into the top of your hand. (Left hand, close to the wrist bone? it'll poke) Crown works great though- no worries about screwing it down, etc.
Of course, the other great thing about RWG is that if you buy the rep and don't like it, someone will buy it from you.
