Of course:
- the 45 and 15 on the sides are "cutted";
- the word BASE is a little blurry (also not sure if it should be on this model);
- the two buttons are in different color than the rest of the case;
- there's the "swiss made" under the 6 and I don't know if it should be on this model (I read somewhere on he forum that it shouldn' be there);
Perhaps you'll spot yet other details.....

You read that 2 posts above yours, and I find this an interesting point. I feel that 50/50 of the Cal.156 that you see do/do not have it on the dial. Both this one here on the forum and this one at Vintagecaliber do have "swiss made" on the dial, both seem like pretty reputable sellers. @vujen and @bigsom could you elaborate?
The more I read about these vintage Zenith chronographs, the more they drive me nuts.![]()
Thanks, that’s great to know !
I’m also wondering if it could be rust at 1 o’clock on this photo, which would mean the case is not gold....
And the color of the case is kind of strange don’t you think?
Thanks! So overall verdict?
The Italian one has rust in the movement but the dial looks very clean with some suspicious parts. I would pass.
The French one has a more battered dial, pushers with wrong gold color with one which has lost its plating. Unless you can inspect it personally, I would not recommed to buy it.
Why don't you ask @bigsom if his Zenith is still for sale?
Furthermore, I believe that the Italian one has the wrong chrono seconds hand, but no expert here.
Why do you think so? Because it is not blued? Or anything else that I miss?
Concerning color: Either seconds hand and subdial hands blued or gold.

And finally, how about the medics version, do you find it ok?

Thanks for the advice @Oku @DSOTM and everyone, your experience and sharp eyes are incredibly helpful !
it looks very hard to find a piece not messed-up...
Those two look fantastic, but well above my budget for this buy. I was hoping to find something decent (even if not perfect but authentic) for around 2K €/£/$.
