Help identifying movement of my Tudor 7956

[Tijlus]

Dear forum members,
This is my first post here, and I hope I can count on your expertise, would be very helpfull.
I have a Tudor prince-oysterdate with the reference 7956. This gold-plated model seems very rare to me and I would like to get more information about the movement. watch 2.jpg

Thank you very much.

It may be rare but that doesnt mean that its worth more. Probably only worth around $600usd at the most if its in good working condition and the plating isnt flaking off. Gold plating was what Tudor did as a cost saver for an entry level gold piece. Not as desirable today because it is plated and a 7956 is very small, around 32mm.

Im not exactly sure of the model that the movement is but I know its what was used at the time on Tudors watches with cases smaller than 35mm.

Here is one that recently sold in the UK for £425

When asking for information about an automatic movement, it's helpful to post a number of straight-on photos with the rotor in different positions. I'm pretty certain it is a modified ETA movement (possibly cal 2782), but it's hard to identify it without better photos.

Are they not all one and the same. The Chiswick watch and the listed?

It's also now on Chrono24 for £1074

Indeed, and the OP did not ask for a valuation.

These were Fleurier-based movements. I have a similar watch with the movement branded "Solar Aqua." Only used in Tudors (well, and Solar Aquas), and arguably Tudor's first "in-house" movement although it's not a "manufacture" movement.

Caliber 390 was also used in early Tudor Subs. I'm not sure if the date version of caliber 390 has a different name.

The caliber 380 and 390 were a larger movement and fit in 34mm or larger cases. The watch above is 32mm and ive only seen this auto movement in the smaller boy size and ladies Tudor watches of the late 50s. Its caliber is eluding me right now

I only put that in there to show the OP that rare doesnt always mean a gold mine.

Very interesting! I am going to look at FEF movements more carefully. However, I don't think it's a Tudor 390 (FEF 380) unless the OP is showing a mirror image, since the balance cock comes in from the opposite side and has a completely different shape. Obviously the layout is completely different as well. Perhaps a different FEF?

Edit: It is also not the ETA I mentioned earlier.

Left is a Tudor 390, right is the OP movement.

As I said above, its not a 380/390 movement. They wont fit in a 32mm case

OK, I am coming across references to a Tudor 1411 movement, and there are examples on the internet that look like this movement. Several people are calling this a Tudor 1411, but I can't find a definitive diagram.

OK, I looked more closely at the watchguy (Christian Dannemann) post, and the caliber 1411 is marked on the front. You can look at this page for more photos of the disassembly, but here are the key photos. I think this is clearly at least the correct "family" for the OP watch. I'm not sure whether there might be some close variants.
