are just barely over 6". I think the 42mm Planet Ocean is really almost too large, but I have ordered the smaller strap/clasp and believe it will wrap slightly better and position the watch so that it 'fits' sufficiently. Right now, it hangs slightly off and can look a bit big on my thin wrists. I believe the EWC is much larger? 46mm or so? I just couldn't pull it off.
My next JLC's will be one of the older reverso's and likely one of the older MUTs if they larger one comes out as expected.
