The most noticeable difference is the bracelet. It’s not like rolex rep, which the gen and rep are not that much difference. The gen bracelet is so smooth, and more bendable. When you wear it, it feels like it grabs on your wrist. The edge of the rep is sharp, and will feel uncomfortable if wear for a whole day.
The other thing is the movement, the rotor color is wrong, too yellowish. It would be great if someone can plate the rotor to rose gold color. The noise is not bothering me, since the gen movement is loud anyway….
