I may be wrong, but have been researching the pelagos recently and I believe the 2 line dial is from 2012 from initial tudor release using an ETA movement. In 2015 they cam eout with the 5 line dial for their own in house Tudor movement.
I personally would want a blue 2 line dial, since the rep will have an Asian ETA in it, that would be more realistic to the 2012 ETA based version
Bad thing, is that when I start researching a watch, I usually end up buying it. Which is very bad since I just bought a gen Rolex and am now broke.
