I would think that actually is a Zenith (136)/Martel 16"' movement behind that dial.
Not the movement one walk on every day, be very careful with that one.
It is branded Zenith but you will find the Compax to be an Universal movement.
Do you have the original case for it too, if yes this watch is a keeper for sure.
Take a picture of the back too so the ones like me get a treat.....
Be very very careful with it or you break my heart! ;)

Uj! As you say something has happened here. The most probably will be OK by a gentle good cleaning.
The minute jumper is intact so that is a bonus, a very brittle part which always is in demand.
So when looking for parts one probably has to look for parts to its base caliber which probably are a Universal Geneve 285.

The Zenith calibers in this series is quite easy to identify they are called like

Caliber 136  = 13 ligne = Universal Geneve 383 (Base caliber 286)
Caliber 146 = 14 ligne = Universal Geneve 385 (Base caliber 285)
Caliber 156 = 15 ligne  = Universal Geneve 387 (Base caliber 285)
Caliber 166 = 16 ligne = ?

My guess is the 285 is the base caliber for the 166 too. 
On Cousine they have some bits and pieces for this one.

But you should practice on some inexpensive ones for a while first before digging in on this one.

To me it looks like Universal 281 Tri-Compax but the one on ranfft is 27 mm this is over 32 mm.

but very close likeness

Yes all these 28X has a close likness since they are based on the same movement.
Your movement is 16"' (Ligne) in size. To convert this to millimeters one has to divide the ligne meassurement with the magic number 0.44326241134752.
So, 16 / 0.44326241134752 = 36.096 mm. So it should actually be a bit over 36mm when you meassure it.
Then we have the UNI-COMPAX, COMPAX and TRI-COMPAX, here it is probably easier to see a picture of the differences on the dial side.
Hope this helps.

      Here is the insert ring for rectangular or elliptical movements: Note that the length is the side with the stem cut out on the spreadsheet (in the picture below this is 15.15: Here is the fake pdf file, again you need to convert to .zip after download to access the FreeCAD and 3mf files.

      Omega cal. 565 - low amplitude

      By JohnR725 · Posted

      as you took the mainspring out what did it look like? It's amazing how much amplitude you can get if the mainspring actually has the proper shape. last week I was doing a 12 size Hamilton and was very much surprised with the beautiful back curvature the mainspring had. Then the watch had a really nice amplitude the group would be so proud it was 350 until I dropped the lift angle down to 38 that drop the amplitude quite a bit below 300. then with the beautiful back curve it still had really nice amplitude the next day. I really wish all my mainspring's look like this as the watch had beautiful amplitude the next day. So many of the aftermarket pocketwatch Springs I see now do not have anything resembling a back curve may be a slight curve and that's about all. They still work but they just don't work as nice as a properly made spring. then Omega as all sorts of nifty technical documentation unfortunately every single corner is watermarked with where it came from who downloaded it etc. very paranoid company. On the other hand I will snip out images like from the document on recycling a mainspring barrel. for instance here's the section on what your mainspring should look like. water damaged a lot of times means rust was there rust on this watch?

      Welcome to the forum, enjoy. It’s highly unlikely you will be able to purchase a new bezel look on eBay for a pulsar watch for repair to find a bezel.
