Blancpain Fifty Fathoms - should I worry about the springbars coming loose?

[Spartyfan6262]

Hello Guys -

I've recently learned that the Fifty Fathoms doesn't employ traditional springbars. Instead, it uses a bar that screws into a hex head receptor inside the lugbar. But knowing this, I'm a little concerned about whether the hex head could come loose during heavy use of the watch.

Have any owners seen this happen? Or is this something I shouldn't worry about at all?

Thank you!
