Its the 42mm, I can't handle much more then that. For me its perfect.:sub4me:
Heres what like since I last bought a rep PO in July of 2006, the updates.
Way improved AR its almost if not exactly like my gen PO crystal.
The pearl, again huge improvemnt and matches the gen very closley.
The end link and bracelet gap is now gone, it looks great now.
He valve is Perfect, by this I mean postion, size, and look.
Clasp works smoothly and divers extension does no fall open.
Now with all that. I have never owned this model in the 21J verison, only the ETA versions, but so far its right on and running well. I have had other reps with this movement and never a problem.
