Hi All

I am picking up a gen Daytona today, pre-owned from a member on big watch forum. He checks out, but knowing what I know about reps I can never be too careful.

That being said, from every pic the case, bracelet, dial etc. all gen. However one fear I have is the movement. There are some sick people out there, and who knows if they swapped for a NOOB A4130. I know it sounds absolutely paranoid, but I would love to have peace of mind.

I am meeting up with the gentleman today. I called a couple of ADs in my area, none are willing to authenticate the watch, even for a fee which I found odd. So I will need to check everything out myself. I am not a full expert, but I have handled so many gen Daytonas I can easily tell from the outside if all is legit or not. It is what inside that bothers me.

So my question would be, are there any tells on the rep movement that I could easily spot? The only thing I could think of is on my previous gen Daytonas the minute subdial had a unique way of advancing where it moves a little bit, and then hits the minute. If anybody has any other ideas, I would greatly appreciate it!!

Thank you very much in advance!

Surely a legit sale would guarantee the movement is gen, and include the option for you to have the watch independently examined and verified by someone with expertise?

This is the gen notice the balance bridge and the free sprung balance. It only has 1 adjusting arm.

This is the SA4130 you will see that it is not free sprung and has 2 adjusting arms. If you see this movement then he is trying to rip you off.

Thank you all! Will confirm once the deal goes through.

I figure I love the Daytona so much, I might as well make it my one and only gen.

You can put gen balance on a Noob SA4130. See attached pic of my Daytona. Unfortunately balance is not the litmus test any more :(

This 4130 rep movement is freaking amazing, will make gen identification harder and harder. Good luck Mate!!

How did you get it to run? Did you make any modifications to the main plate?

Gen balance doesn’t require any mods to run on Noob mainplate
