WATCH POP

Hi I have a zodiac automatic movement which i think is a model 11A but on the other side it says BREVET 1250, its unusual because the oscilating weight doesnt fully rotate it has spring end stops. Is this movement worth restoring and if so what watch would it have come from? ... with either 15 or 17 jewels operating at 18,000 beats per hour. It was introduced around 1940. The bumper autos were manufactured by a number of movement makers prior to them giving way to the generally more efficient full-rotor automatic designs we are more familiar with. The 'bumper' designation stems from the bump that can be felt as the rotor rebounds off the springs.
'Brevet' is French for 'Patent'.
I don't know what Zodiac watch this movement would have been used in.
The article below shows an Omega bumper automatic movement being serviced. Omega bumper auto...
Paul. Hi thnx for that, the movement has the jewels missing from under the balance wheel but the staff seems intact, I thought about repairing it but when its finished i dont have a suitable dial and case and no idea what it should look like so maybe i will shelve this one till i find out more about the Zodiac watches.
