I am about to buy a 5001 Portuguese automatic (steel; blue hands).
Somewhere i have read that there is a difference between pre- and post 2007 models.
i am curious to know what these differences are and whether they materially affect the quality of this, otherwise stunning, watch.
finall, is there any way to tell the production year of the watch by looking at the reference numbrs on the back?
thanks in advance
