So it was running then stopped , yes.    Remove balance and check the power to the pallet/fork, does it snap back and forth if not remove all power and remove pallet/fork  and put a turn on the spring, does the train run free and the escapewheel does a little reverse at the end of power.. If not re check the train and mainspring barrel. mat be a bit of dirt in the teeth, bent or broken tooth. once having attained the treedom of motion refit the pallet/fork and recheck the action if ok re fit the ballance and check the alignment of the impulse pin with the pallet/fork. At rest it should be in line with the impulse pin and central. a read of the attached will help in understanding the escapement.

Working on a Smiths De Leluxe. Filthy, cleaned, reassembled. Balance back in, running well, I've cracked it.  No, five minutes later not running. Mainspring OK. Any ideas?

Nice. I like Smiths. I'm  waiting to pick up an Everest at a good price.

Rich you know the issue  could be lots of things right ? You also know you are going to have to at least take the balance out and check that there is power to the escapement when you have wind on and resistance at the barrel end.

Plenty of power, wheel train running smoothly, started again, going really well. Good amplitude, stopped again.

When you say it stops when you change the orientation , in what manner  PU  PD   PR  PL  ao  Du  Or DD..     you may have a cracked/chipped jewel .

I think the pivots on the balance staff are broken, not enough to stop it running but enough to make it stop running when moved.

Judging by the pictures the stud position is wrong or the terminal curve is compromised. Remove the balance from the balance cock and re  check the contcencicity of the spring. If the spring lays ok then re fit to the cock keeping the same profile.  also whilst the balance is removed check both pivots, one or the other/or both may be damaged.

Here's the hairspring, totally lopsided. Stuck together on one side.  Tried cleaning again and demagetfying. Still the same.

Richy babes. It looks like someone has fitted a new hs without forming the end curve. There should be a bend on the spring back from the regulator arm, this is to extend the last curve further out and be kept parallel between the stud and the regulator arm pins. If there is a bend then its been taken out to some degree

 👍The stud doesn't look in line with the coils.

I'll give it a go.

Ok, I've got it to about 180⁰ only another 100⁰ or so to go. I might not be a rank amateur anymore but as you all know servicing and repair are two different things.  I'm getting proficient at servicing but repair is a steep learning curve.

Did you manage to sort out the hs rich ?

      Stem removal after fitting hands

      By Neverenoughwatches · Posted

      So leave off the seconds. Stand the movement on its edge, its the dial edge that rests on the pad ( either rubber or cork , something that wont slip ). Use a finger of your left hand to hold the movement upright,  right hand presses the release and flicks out the stem. I do it this way so i can see what I'm under a microscope. But you could hold the movement between two fingers of your left hand, its the right that has to manipulate the stem out by pushing the release and flicking out the stem with  right ring finger nail. Sounds more complicated than it actually is. I guess you could fix a push pin to something solid, then all you need to do is push the release against the pin, leaving your right hand completely free to pull the stem out.

      Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.
