When I started collecting watches, I bought the following Zenith watch. I didn't do any research, I just bought it by impulse because I liked the look of it and thought that even if it was a redial, I wouldn't have lost too much money on it.
Somehow the watch didn't get any wrist-time and I completely forgot about it. Until today, when I cleaned up my desk and found it under a couple of letters.
As I wasn't even sure if it was a real Zenith, I opened the case (No, these marks on the caseback aren't proof of my wrongdoing, they were already there when I bought it ;-) )
Here's what I found out. But let me tell you first that I have no clue about Zenith, as I collect vintage Omega and Breitling watches.

- About the Movement:
1) It appears to my untrained eye to be a real Zenith 2572 PC.

2) As I read online somewhere, the number 380 on the caseback indicates the case should feature such a movement. Which seems to be a good sign so far.

3) The inner caseback shows signs of wear from contact with the rotor.

4) The movement looks as it is in urgent need of a service as the rotor itself doesn't easily rotate.

Questions concerning the movement:
where's the Serial-number?
What about the regulator? Is it really supposed to look that way?

- About the watch as a whole / Ref. Number:
5) I just found one single watch online which looks the same way - on ebay (Hongkong). For Omegas, that would be a good indicator that it is a redial. But as I know next to nothing about Zenith watches, I'm not even sure what the ref. number is...

Question about the watch: Is it a real model or a fake / franken / redialed one?

Here are some pics.
Any informations are much appreciated!
Ps, if it helps answering my questions: I live in Switzerland and also bought it here.

Edited in order to eliminate typos as I'm writing on my cell phone.

 

Nobody?
Do you need better pictures and/or more information?

 

Its a nice watch. Probably a real one because its not the kind there would be a lot of incentive to fake. I mean, its not gold and probably a 70s watch. Very wearable being an automatic imho.

 

It's real and everything about it is legit.

 

I don't have any of my reference material with me as it is somewhere on a container ship, but the reference for this one is the entire number on the case back. There are no serial numbers on these movements unless needed for COSC certificates.

 

Great, thank you all very much for all these helpful informations!
