The insert blue color looks pretty good, hard to tell for certain with only one pic. The marker cutouts are either rough, or it's had a paint mod that wasn't done perfectly or has worn away some. That aspect of it is substandard, but it would be less noticeable at arm's length. Markers are thinner than gen, but most non-gen inserts are that way. The triangle looks particularly bad - paint gouged or peeling up. Since the blue color is good, a marker strip and re-do the paint mod could make it a nice one.
Yea buddy but this is a rep made in China what you expect for that price ? Your watch has a lot of other issues that are „well done“ but not correct (dial Markes, Hands, SEL, Movement, bezel color....) A gen is now selling for over 12000$
but notice that the numbers of this insert are white, the gen numbers are more silver/gray. But there a guys in the forum who can repaint that for you to mach the correct color.
