Well this is very interesting. Can you measure the OD of the insert? It looks like it might be gen-spec (37.65mm). That would be a very big upgrade for BP. Also the bezel not being held onto the case with a circlip and the crystal gasket being full height are nice improvements. There is also a standalone crystal retaining ring, and presumably a hytrel ring.
Hopefully there isn't a wire clip between the bezel and the retaining ring, that would not be fun. The gap there looks a little big in one area.
I always separate the bezel from the retaining ring before re-pressing the crystal, though it is possible to do so with those parts together as they are in your pics. It can be easy or not so much depending on the thickness of the crystal gasket and the space alloted for it.
And while not correct for model, the springs and balls bezel is superior even to the gen 5 digit arrangement. Just look at all the issues with the RAFARF 5 digit bezels. Coupled with a VR3136, this rep is putting in a bid for sleeper of the year right here at the end.
Since this is essentially a 6 digit bezel maybe some would find my
6-digit Sub crystal and bezel swap thread useful.
