I was disappointed with the 001... the metal bracelet I got had a bent part at the clasp end, so it was sent back, and a screw fell out of the crown guard, so that go replaced (eventually) by the dealer... as a result, by the time it was in shape to be worn, I had other PAMs that took precedence - PAM188, 192, 196, 029 and 063... as well as the 036s that I have, and the 001 never got worn! It's just stayed in the drawer all this time.
I haven't worn the 028 yet, not until the Palp crown comes through and I can get all the mods done at the same time: date wheel, PVD, relume etc.
