That model above has a faux PR indicator. There is only one version of this with functioning PR and it is not even close in terms of the case, crystal, dial and movement. There have been rumors that the factories are working on a 'real' PR movement for some time with little news in the past 2 years. Going gen makes good sense on this model, or maybe just going for the 422 without the PR. If PR is what you're after, the 27, 28 & 57 may be your best options albeit different case design & size.
