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.

      How do you thread a screw on the lathe without shearing it off?

      By nevenbekriev · Posted

      I would repeat what @nickelsilver says, and even more. I have at leas 10 old thread plates and I have never seen one that will cut like a normal die. I don't know if they are completely worn or have never been sharp enough, but I find them completely useless. And, for the new Indian ones, I have heard only bad things. For sure, if one tries to cut more thread on a winding stem, this hole of the plate is ruined. Further more, I have bad experience with all watch size thread dies that I could buy from the available machine  tool shops here. They could not cut normal thread even on brass rod. The size was significantly smaller and the pitch is like it should be for the claimed size... The thread shape was bad too. I will explain how I do threads. I use lathe that can cut threads and thus I can prepare perfect taps. I use milling attachment instead cutter in the tool post and so I can cut thread even on hardened rod. But I prefer to harden the rod after thread cutting and temper it only to light color change as to have the maximum hardness. Then I make a tap out of it by grinding. I prepare my dies for screw thread cutting with the taps I have prepared as described. In watchmaking, dies exist and are often used that are not cutting, but rather forming the thread. They are like nuts and don't have cutting holes and edges. This kind of dies I prepare and use. You will need soft steel plate , drill a hole in it, then cut thread, then make chamfer on one side, repeat the thread, harden. You can temper just a little or leave untempered, depending of the steel You use. Using such die is with soft steel rod (or completely annealed). Good oil is to be generously applied. The rod has to be with smaller diam than the thread size (about 0.8 - 0.9 x ), the diam is better determined by tries. The rod elongates by the thread forming too. When I have to make screws from harder material like SS, I just cut them on the lathe. You screw needs hardening and tempering to be finished as real screw.

      You could make a guide/jig. Cut a slot in a piece of metal approx the same thickness as the screw head, then drill a hole (screw head diameter) in that slot.

      Thanks so much for quick replies. I got some watch repair tools ordered, and will get back with pictures once I removed the back lid and get into it 🙂
