I'm on the borderline, most of my watches fit - usually on the last hole/largest link - JUST, my Omega Seamaster at it's largest with standard links fits but for long periods sometimes feels a little tight, my lunatik band actually fits well but the extra silicone which should attach to the retaining clip doesn't clip in. My pebble with a NATO strap fits nicely but on the last hole, i've measured my wrist and even printed out the template and they all seem to be JUST about there so hoping the fluroelastimer may have a bit of give in it, once again i'm hoping for 3rd party straps to come along fairly soon which may give me some more comfort!
