I have much smaller wrists than you and I find it to fit wonderfully. I wear it mainly at work, and more often than not on some form of NATO. I have the bracelet and rubber as well (it comes with the watch), and I find the bracelet to be fantastic.
Here's mine on the wrist. Perspective makes it seem oversized, but it's not, if seats perfectly right in the middle of my 7.5" wrist.
