  1. Look at the coils of the H/S as you try to demag it. I beat they are vibrating all over the place, basically they are moving within the magnetic field lessening the demagnatising effect. Try sitting the hairspring carefully in some rodico so it can't move as much and try again.

  2. A funny one arrived today.

  3. I went to school for computer engineering so i'm not too afraid of an electronics project, I wish radio shack was still around as I'm pretty impatient with waiting for parts. From what I understand, it's just a coil producing a magnetic field and you slowly pull the watch away to demagnetize. It's been a little while since I did any EM calculations but it'd be a fun side project. Also, the way I see it, the field needs some young blood to keep these time pieces going. I hope I can learn a lot from the more experienced folks. Sent from my SHIELD Tablet K1 using Tapatalk

  4. There seems to be some confusion about oiling a watch escapement. Use the finest oiler The pallet stones are to be oiled. Never oil the pallet pivots and never oil the pallet fork. Oil the escape wheel pivots. Oil the balance pivots You do not need to oil the teeth of the escape wheel, the oil on the pallet stones will do this by the rotation of the escape wheel and its coming into contact with the pallet stones.

  5. I rarely see Breguet coils that were not distorted... You must twist opposite of the highest point, using 2 tweezers: there is a good chance that A is the right place. The stud should not go much lower (maybe a bit) else it may touch the spring "dial up". The coil in the regulator pins area must be concentric, looks different here. I also suspect, the whole curve after the knee is a bit too far outwards. Frank

  6. That device is actually incredibly simple, albeit slightly crude. The circuit appears to be as follows... Part one is mains in, through a small switch (possibly mains rated, possibly not, but given the long shafted plastic button, not something I would worry about) which energizes a good old fashioned 1980s style wall wart transformer, from the days before even the cheapest wall wart had a switch mode power supply in it. I can't see the output side of the transformer, it may have a small resistor to load it up and increase the magnetic field, or it may simply be open circuit. The magnetic field from that does the actual degausing. Part two consists of a high value resistor (Brown Black Yellow = 100k Ohm) and LED (across the mains, slightly dubious practice, but not that dangerous), the LED only lights when the button is pushed. One thing I would recommend is to ensure you have a 3A or even 1A fuse in the mains plug. From a safety perspective though, as cheap goods from China go, it looks reasonably safe. If the switch fails closed, the thing stays on (not a problem), if the switch fails open it fails to energizes and the light stays off.. also not a problem. The only issue is that the unit has no built in fuse, so you would be relying on the plug fuse to blow if the transformer winding failed shorted, hence the comment about using a 3A or 1A fuse. It certainly looks a lot less likely to burn the house down than a lot of badly constructed modern cheap wall warts, but I would still recommend unplugging it when not in use. I might even get one. At round about a fiver, shipped from China, it is probably as easy and cheap to pick up one of these as it would be for me to go through my electronic scrap bin to scavenge the parts.

  7. Wow that's a keeper. Hopefully it'll keep Mao or less good time when serviced...

  8. Place the component to be de-gaussed on the Chinese unit. Press the operate button, for a couple of seconds then Slowly remove the component to about one metre away. Switch unit off. Your component will now be de-magnetised. Moving the component slowly away whilst unit is switched on reduces the E&H field with distance and this slowly reduces the AC field strength by inverse square law. Mine works very well.

  9. I would make sure it is in beat. As OH states worn bushing can play a big factor as well.

  10. Nice, that looks almost brand new. I've got a couple of jump hours, but mine are in the still needing a lot of TLC pile. That's the trouble with my self imposed budget, they almost invariably are in need of work. Speaking of funny... ... a good old mechanical from the land of the smoking chairman, (at least I assume he is smoking) by way of some random corner of ebay. It hasn't arrived yet, but when it does, I'll be sure to post the wrist shot of him moving is wrist, on my wrist here. It was 2nd hand, so in to the 404 club it goes, assuming it works, or I can get it working.

  11. For what its worth, this ebay search might turn up something to your liking. "watch case" fit movement Without knowing exactly what kind of case you are looking for, it is difficult to be more specific.
