·I’m not expert in these models, crown is uncorrect, dial looks good to me but wait for best opinion
See what you think of this one

S sdd7820Thank you for sending this over. The crown looks to be a replacement correct?
Possible. Not all chronographs had a Zenith crown though and it’s hard to say when they started etc This pic is from an early 50’s Zenith catalog
I periodically look at these Zenith chronos, unfortunately many of the ones I see especially on eBay seem to have redone or partly redone dials. I think there was/is a nice 3 reg 156 one on the OF private sales forum (I have no link to the seller), and I am keeping an eye on this 156d on eBay:

I have however just recently acquired two Zenith grails, so it’ll probably be 2020 before I pluck up the courage to tell Mrs K I’ve bought another watch...
This is a great example of how this whole process can drive you crazy
I have been following all along as a way of learning about vintage Zenith watches as a prelude to honing in on one I would like to own ( and that I can afford/justify/rationalize owning )
A key takeaway from this thread is the desirability of the Calibre 146 Zeniths
Now I have to go looking for information on Calibre 156 ( D )
🤨
Cal 146 and 156 are basically the same, just different sizes (14''' and 15''', respectively). Both made by Martel. Of the manual winding chronograph movements that Zenith used, the 143-6 by Excelsior Park is my personal favorite.
Dan,
In which Zenith references would one find the 143-6 by Excelsior Park?
Does you post imply that Zenith used movements that were not made "in-house"?
Bob
None of the movements being discussed here were in-house. The 146/156 were made by Martel (also widely used by Universal Geneve with different caliber codes, e.g. UG285/287) and the 143-6 was made by Excelsior Park (also used by Gallet, again with a different caliber code e.g. EP4). Obviously there were some minor differences in the way the movements were finished, but the base movements were shared.
Was the movement inside the original El Primero made in-house?
Yes. The El Primero movement was made by Zenith/Movado, and if you haven't read about the history of the first automatic chronograph movement, you should google the story and read about it. It's quite interesting. There was a three-way race between Zenith, Seiko, and a collaboration that included Heuer. Although Zenith named theirs "El Primero", it is still somewhat debated which was the first.
This leads me to my noob question - do the knowledgeable members here collect watch models ( ie: Sporto, Defy, etc ) or do they collect movements ( ie: 146D, 135, etc )?
Thanks
This is incorrect!The DP and HP movements include several upgrades like flat coil and shock proofing but are not chronometer movements.
