I think the hole in the endlink is just a bit off from a gen endlink, which makes it fold higher when you wear it. It's weird because you can't tell the difference when they're just lying down. Eh, maybe I just have a one-off. Bezel is a bit stiffer than gen and insert is slightly shinier.
Date font is slightly fatter on gen but this is something that doesn't bother me. Dial is also slightly different (pretty much the same as the Noob). Gen has a sort of wavy/grainy texture, rep is flat.
Seamaster logo is slightly fatter on gen. Has sort of a 3D feel to it.
But again, all of this is really only noticeable when you compare the two side by side and and look at it from different angles and light. It is that minuscule. You really need to start looking for these things to actually notice them.
I mean, these are so good that I'm pretty sure you'll even fool an AD with them for a few minutes (not that you should do that of course
).
I also like the fact that they replicated the quickset feature from gen. First step when you pull the crown out changes the hour hand (and with the hour hand, the date). The second step sets the minute hand. Oh yeah, and the crystal. The crystal is perfect. It's as clear as a gen one and has the same AR shine to it, no need to get another modded crystal.
