Screw down crown / bezel question

[ejcoreup]

Hello all,

My 16233 has a custom bezel that it was purchased with. When buying it, I didn't really look at this closely. To me, I have minimal Rolex experience (this was my first one), it looks like the screw down crown is being blocked from screwing down all the way by the bezel. Does anyone think I'm right, or does this look normal (how far it's fastened down)? I think it looks like it's, definitely, not fastened all the way, but I could be wrong. This raises some concern for me, not about the purchase (I love the watch), in the area of using it in water. If it is indeed being blocked, I'll avoid using it in water at all. I have avoided water up until this point. I have been looking at it for a few weeks and forgot I could get some opinions from experienced Rolex enthusiasts on here. Here are some pics. Thanks in advance for any input.
