The gen has both fish logo and Probus Scafusia crown. The latter comes in newer model. I would suggest paying attention to the alignment of the pusher and the crown. On the genuine, the crown is slightly higher up. The genuine is also slightly thinner than the rep. After modification with genuine movement, it looks closer to the genuine due to thinner bezel. However, this does not change the position of the crown. It gets so close to the genuine that I am pretty sure very few will notice this "flaw".
