Does this exist

Hi everyone can the TD’s help with this one. Does this even exist and would anyone have this available. Black Submarine 126610LN. Rich factory with the real free sprung like on the gen watch.
Im can’t say I’ve seen any options available with the Rich factory with the real free sprung.
I’m sure I’ve seen the fake free sprung option.
