8 Day French Strike on a bell. It has count wheel striking. Original half moon hands. I don't think its the original pendulum, it certainly isn't the normal type I would expect to see. If you remove the bell you should see some numbers, one of the set of numbers on the back plate should match the numbers on the pendulum. That is the way of telling if the pendulum is original, The other set of numbers tells you the length of the pendulum in French measurement, I can't remember which one. White enamel dial, I see a touch of chipping around the key hole on the time side. Fine regulating can be made by the adjustment jut above the 12.

That back plate number is the movements serial, the pendulum should have the same on it, I have never seen a hexagon shape pendulum before on a French clock. Someone has made a mess of bending that crutch to try and set it in beat. The oil sink on the large wheel loos a bit suspect going by the photo. When its all cleaned up movement and case you will have a nice looking clock.

Hi You might find this interesting reading if you are interested in french clocks.  One thing to remember with french clocks the pivots are glass hard and brittle so when dismantling ,cleaning and rebuilding be very carefull and dont use force when putting the back plate on and be gentle when aligning the pivots and holes and you will be ok.

    • Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!
    • Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?
    • Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.    
    • Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?      
    • Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
