Robaer, if you need a case that will accept a gen dial, bezel+insert, crown+tube, gen crystal, and gen springbars, a good old MBK does all that.

gen dial ---------------------------------------------------------- *checked*

gen springbars - you will need one of the modders here to help you with this one.
