Hi there JD, that is what you call a bumper movement 

A bumper movement is a type of self-winding, automatic movement.

However, unlike a modern automatic, which has the rotor spins a full 360 degrees, a bumper moves back and forth at about 120 degrees.They are fun to wear. You can feel a slight thud as you turn your wrist reminding you that you are wearing a bumper. It is an interesting method to wind the watch that avoids infringing on full rotor patents.Hope that helps 

Cheers Graziano

Looks like an AS1171 which as @Graziano says is a bumper movement. As such the oscillating weight doesn't make a full rotation at all but swings back and forth through an arc of about 170 degrees, bumping off the buffer springs that you can see.

I did not even know that it is called dressing (English is not my mother tongue). Interestingly I have not read your advise or any other advise after the video for dressing and I almost did the same thing on my own following common sense. I worked on my brass tweezers internally first - the only difference was that i used grit 800 and i did not fold it only worked on one of them at the time -, then i worked on them along the sides - perpendicular. I am sure it is not perfect as I did it more or less the first time, but i am sure it is a way better then they were before. I also bought a pair of Dumont tweezers as you are not the first one who said the same thing but with different words: "it was like going from a riding lawn mower to a Rolls Royce". However i have not felt that big jump, i bought a set of 8 stainless steel tweezers from cousinsuk and they are quite ok. (They were advertised as "Superior Quality" but could not compare them to something else - before the Dumont - as it was my first set ever for watchmaking) Well they are good or I am just not experienced enough to feel the difference between those and the Dumont. When I look at them under the microscope the Dumont looks better though. ?

I know: practice, practice, practice.

All in all very good advice, thank you. ?

Thanks Mark. I will be stripping it down and getting it working and looking good again. Cool watch that I got in a trade for work.

Very appreciated. I was stumped when I first saw this movement as I was thinking “where the heck is the rotor “ ? interesting but simple design. When it says incabloc , what is the company that produced by his watch?

I don't know who made your watch I can't see makers name but back in the mid-20thcentury, the “Incabloc” trademark was a sign of quality and excellence for watches, to the point that brands would print it on their dials, and I have seen incabloc on rotors just like yours.

Thanks. I do have another 24 Jewel incabloc. Btw, this watch has a radioactive radium dial.

 I have got two bumper automatics( AS made specially for Mido), with the original MS still in the barrel, a detached special spindle. Though a regulare type spring replacement can't be ruled out, I wonder what original MS in my watch is telling.

 I suggest you check and try to source a MS for this before investing time in it.

Hi Joe, please delete it as I didn't even think about that, I don't want to cause any problems. Sorry about that.

Hi Graziano,  I don't think there is any problem with you post.

I find this gifs very useful specially helpful to me when I try to explain things with my broken English.

I was just asking for your permission to use it, playing polite, didn't want to just steal it.

      Is this a 'hack' ?

      By nevenbekriev · Posted

      OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.

      Any tips to correct a sloppy error?

      Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.

      Setting lever spring

      By mikepilk · Posted

      The stress is the force (on the spring) x distance. The maximum stress is at the bottom, and decreases up the arm. That's why they always break at the bottom. I used a round file, then something like 2000 grit to finish. I gave the rest of the arm a quick polish - no need for a perfect finish. Just make sure there are no 'notches' left from cutting/filing. The notches act like the perforations in your toilet paper 🤣

      Any tips to correct a sloppy error?

      By Geotex · Posted

      It's probably a cardinal rule for watch repair to never get distracted while at the bench. Yesterday, after finishing a tricky mainspring winding/barrel insertion (I didn't have a winder and arbor that fit very well) I mentally shifted down a gear once that hurdle was passed. There were other things going on in the room as I put the barrel and cover into the barrel closer and pressed to get that satisfying snap. But when I took it out I realized I never placed the arbor.  When opening a barrel, we are relying on the arbor to transfer a concentrically-distributed force right where it is needed at the internal center of the lid. However, when that isn't present it's difficult to apply pressure or get leverage considering the recessed position of the lid, the small holes in the barrel and the presence of the mainspring coils. It was a beat-up practice movement so I didn't take a lot of time to think it over and I pushed it out using a short right-angle dental probe placed in from the bottom, but that did leave a bit of a scratch and crease in the thin lid. I had also thought about pulling it using a course-threaded screw with a minor thread diameter smaller than the lid hole and a major diameter larger, but that may have done some damage as well.  Thinking about how this might have been handled had it been a more valuable movement, is there a method using watchmaking or other tools that should extract the lid with the least damage?

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      🤔 what happens if lubrication is placed directly on top of epilame ? Making a small groove so the lubrication doesn't spread across the component but what if when lubing a little overspills and sits on the epilame .
