I have this one but is too high and doesn't fit, and it seems to be same as yours...I've got you covered. DM sent.
Don't believe that's the GMF, which has the date wheel properly placed relative to gen. JVSF, which I believe that is, has a smaller crown (more similar to gen) than the GMF, but wrong date wheel position. Not sure why GMF factory hasn't figured this out yet.

If only the SH/VR3285 wasn’t such a crap shoot of a movement. I was servicing a GMF explorer 2 movement yesterday (it was a brand new watch) and I found rust on the setting lever spring (see pic).
This is quite a hard problem to solve. If the part were all stainless steel I’d simply sand off the rust spots abd then dump the part in hot citric acid to passivate the surface. But because this part has a brass wheel peened onto it, if I tried to passivate it, I’d destroy the part through galvanic corrosion. (Or at least that’s my understand, I’m a physicist not a chemist).

Hi guys,
As I'm planning to swap the fat crown with a gen one I'd like to be sure:
First = to get the right one (should be part number B24-724-0-G1 Milgauss, SkyDweller, Explorer 2, AirKing).
Second = Is the gen crown plug and play with stock gmf tube?
Is there anyone who already did it?
Special thanks to @dogwood for his insight on tube size which turned out to be 3,95mm
Fat crown on stock tube for reference:
What it's scaring me is the size of the hole of the stock tube too large or too small for gen crown pinion.
Some months ago I tried to fit a gen DJ41 crown on a Clean v2 Datejust 41 and hole of the stock tube was too small to allow the crown to stick in.

The genuine 724 crown won't fit the case tube of the GMF explorer (case tube is too small in diameter). You will need to have a Gen case tube installed into the case.Hi guys,

rumor is that Cf will release an explorer 2 with dd3285 in March.
Yes it will. With modification. Case will need to be drilled and tapped. And countersunk to allow the crown to sit flush.
Had it installed on mine.
how's the movement holding up in these for the people who own them? looking at getting one but read a few reports of it being unreliable
