Great post and excellent guide that accurately discerns the differences and variations between versions.
I pulled out my Blacksteel V2 and noticed that according to the lug stamp, mine is manufactured in 2016, as per your guide
Everything you mentioned on the V2 is present on mine, except that the BS seems to have the brass colored sub dial tubes. Visually, I love my V2 Blacksteel; and so far, the movement has been running strong.
I have a feeling that your pictorial will be a large help for many. Thanks for this contribution to the forum.
