Like you, I received my 399 along with the special box set (size of a coffee table if I may add) back in X'ams of 2012.
To this day, I continue to wonder how on earth such mistake could take place.
Given the PAM 399 was a SE with only 100 pieces, not to mentioned the first 50 was to be sold in tandem with the PAM 398, such glaring mistake is even more incomprehensible!!!
I wear every time piece I bought, believing that watches are meant to be worn, and not merely a show piece somewhere in a safety box. Yet with this 399, I can't seemed to get myself into wearing......
