Does anyone have any idea what this might be ? It came with a joblot of vintage tools. All it says on it is   The Xray.

Hi all, sorry a bit rude there I rushed that post, my daughters dog decided to flip out over Cyril the Squirrel.  Good evening everyone I hope you are all well. Any ideas on this random object that may be watch repair related.

Could you make a  mainspring with it?  Not sure yet if that's what it was used for, but...*could you* use it for making a coiled mainspring maybe?

I don't think so. I actually have 2 of them. The name " xray " to me  is suggesting improving the view of something that is otherwise obscured or being able to do something blind. I'd love to know what. I'll take some more photos of it with parts of it moved around. Something might just click for somebody.

It has a small hole through the middle of it and the outer plate is divided  up into 100, not in degrees just 100 divisions. The swinging arm locates into the second pin, then both pins screw down to lock the pin in place.

Here's a thought. Could you place a balance wheel/hairspring complete into the middle of it so that the staff goes into the hole and the impulse jewel sits in the radial slot. Use the swinging arm with the two downward pointing prongs to somehow clamp it in place and then you can rotate the H/S collet around the balance staff a measured amount to correct beat error.

I'm not sure how the clamp would work or if you would hsave adequate access to the collet though.

Ah ha. My good friend. I think you might be onto something there.  As the name suggests.  The impulse is difficult  to see and line up on the plate when  surrounded  by the train and pallet. I'll give it some thought later and let you know.  Good show sir 🙂

It's the prongs that are in the way of the balance wheel hairspring and staff. And the roller table is too far up the staff for the impulse to locate in the slot next to the pin. Plus you are taking the cock off needlessly as well. I usually  stick the cock down with rodico and carefully lift the hairspring  out of the way enought to ease a driver into the collet.Hmm 🤔

I notice that the example featured here also has a radial arm which rotates around the central axis and has what appears to be a blade like tip. I wonder if this is maybe to poke into the split in the collet so that it can be turned.

You might still be right. I'll have a play later.

I'm thinking youre right .Seems of a bit of a long way around a simple job though don't you think ?

      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.

      Stem removal after fitting hands

      By PeterS · Posted

      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.

      Stem removal after fitting hands

      By Neverenoughwatches · Posted

      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.

      Yes I understand that. What I’m asking is, after the hands have been fitted, it’s been checked that the hands do not touch etc. then I need to remove the stem to fit the movement in the case. I have the push type, I need to turn it upside down and push the setting lever post and pull the stem out. But of course the dial and hands are in place and I have a glossy dial with lume dots and I do not want to cause any damage while it’s upside down pushing on the post of the setting lever.
