Here are some comparison photos. First is a Phong case with 702 crown:
Here's a Josh case with chunky rehaut top and stubby CGs. The 702 crown makes them look pretty good:
Mine was tight out of the box, and I had to cobble in a link from a 7206 to make it fit. I just unfolded the middle link blade and slipped it in there and refolded it. It's right next to the clasp and you can barely see the rivet heads even if you're looking for them. Of course I have wrists like Popeye so you might not have trouble. And... the 9315 clasp is longer than a 7836 clasp so that might give you enough wiggle room.
Here's one I posted on WUS. Someone finally noticed the date and mentioned it. I replied back that most people know a GMT can display dual timezones, but most people DON'T know it can also display dual dates. Hence the concentric date rings in the window, both showing it's the 3rd of the month.
And they believed me.
