The first SN is indeed 125001. I have known it for a long time from my SN tables, and thought it was widely known.
I have an average of 7 records in each thousand going back from 129k, and then suddenly at 125k, it ends. Lowest SN observed so far: 125,255 (1903, caliber 35 hunter, 21 jewels, no chronometer balance, no Precision marking). The Precision marking first appears at 128k, by the way, even though there is no change in the quality or type of movement at that SN.
Maybe I should go ahead and analyze the SNs 125-150k.
