Well... For sure if you are looking for a better one, dial needs to be changed.
On the movement side, I would suggest doing a Tuiga version with closed caseback, that will reduce the number of flaws. The area around the screw on the rotor is still wrong. On the gen 7750 it should look like this:
I notice this very clearly when holding the gen HBB: rep crystals are too thin. It should slightly be thicker to match the gen.
The strap of the first generation is very good, very close to the gen too.
The engraving on the rotor is not 100% correct too (the font is too thin/squeezed on the rep).
Most importantly is the gold weight can't lie.
The engraving on the caseback needs to be improved... It just seems like "unfinished" job with rough parts.
Should check the caseback crystal too... It should have sapphire crystal.
