I have serviced a 1333 omega .But it won't work even if the coil and circuit is okay . I have tested the coil. The circuit have pulse and i put it on a vibrograph it looks good. But won't run . Wheels runs smooth . i think i have tested everything but nothing seams to work. I thought a could have put some of the wheels upside down . But looked a the 1337 service here on the forum . And can't see anything i have done wrong . It's eating me up that i can't fix it.  Can it still be something with the circuit?

Did the watch work before you serviced it?

As you've tested everything what's the current consumption of the watch?

One thing you might try is isolating the gear train from the rotor. In other words put only the rotor in and providing you can see it see if that moves when you apply power. That's a rather interesting rotor if it was demagnetized or didn't have its proper magnetic properties that would be a reason it wouldn't run.

Hi   Daft question I know but have you got power to the circuit.

I have put it in a vibrograf where i can see the pulses from the quartz crystal. But the rotor isn't moving . And if i put a multimeter over the 2 prongs on the circuit it gets a puls every second . The coil should be okay as i measured it to 3 ohms. DSC00479.thumb.JPG.e832ddd1ba9ad6a4dae793a055e74322.JPGDSC00480.thumb.JPG.ca5bdb18507edd87164705f37c985c89.JPG

The minute and second hand moved before i serviced it but now it's not moving. I can get it to move a little bit but stops after a few seconds. Good tip with removing all wheels except the rotor.  I will do that . Should be easy just to remove the wheel next to the rotor . Could very well be the magnetic on the rotor.

Where are you measuring the pulses to the coil?


It may simply be the case that the contact between the coil and the PCB is not too good (open circuit, or high resistance, due to dirt/oil/corrosion on the PCB pads. If you can measure (carefully) on the coil itslmf, or better yet, if you have a small compass or hall effect sensor to pick up the magnetic pulses then you will know if the coil actually works.

Is the rotor tuning freely? Is there any magnetic debris stuck to the rotor?

As all the component parts seem to be in order on their own but not in the whole something untoward is happening, As Andy remarked the coil /circuit joints, or  a stuck up rotor.  Can you see if the rotor turns as it receives each pulse, If it is then there is no connection between the rotor and the train. Might be damaged wheel teeth or a damaged rotor gear.

Tinkered with it today. Did as JohnR725 said and run only the rotor . Worked . And when i put the wheels back it started to run. No idea why or how . But as is now it's working . I am going to let it run . Need to adjust the hour hand a little but at least it's working.  YAAAAAAAAA. DSC00483.thumb.JPG.706c39c52ad00f2cfab074bc97a308ea.JPG

Found this again the other day. The hour hand is standing still . The minute is moving since i serviced it.  Why is that? The hour hand is turned by a magnet instead of a cannon pinion. There most be something with the hour magnet. Finding parts for this movement is almost impossible.

Since I can only see one coil, in the examples I found online, then I presume from your description that there is a small magnet on the minute wheel that causes the hour hand to "click" at the top of the hour.

This seems a strange arrangement, given that I can see a bunch of gears there too, Why use a magnet  when you could simply gear the hour wheel from the minute wheel. Can you provide more pictures of the way this works?

Could the issue be due to drag caused by dirt or corrosion, rather than a problem with the magnet.

Time for some close magnification work to inspect gears and pinions I think.

      Balance spring fell out of regulator pin.

      By Hawaiikook808 · Posted

      Thank you so much, Hector and CJ. I appreciate the tech sheet and the video. Gasp, I think I will make the attempt. What's the worst that can happen? I think there may be a new balance complete in my future, though.  I'll update the post and let you know the result. R, Frank

      Movement holder made with 3D printer

      By Waggy · Posted

      So here is the new base (v 2.1), I made it so that the base will fit over and swallow the stump of the hand pusher tool (or at least my clone of the tool), I also reduced the OD of the bottom skirt a little as it looked/felt a little large, here are a few pictures and the fake .pdf file which you need to convert to .zip once downloaded.   The cut-out seen on the below image on the bottom of the base should swallow the OD (40 mm, +0.1 mm tolerance) of the stump and the height of the stump 9.5mm (measured to 9.1mm, but rounded to 9.5mm) - let me know if this works for your tool.   Note, I think you may need to print supports for the new internal shelf created? Here is the fake .pdf for just the FreeCAD base file and 3mf files Modular Movement Holder.pdf Here is the fake pdf for complete set of the new base and ring FreeCAD/3mf files: Modular Movement Holder base and ring v 2.1.pdf However, I'm wondering how often you could use this feature, adding the dial usually increases the OD of the movement, so you would need a new (larger) adapter ring tuned to the OD of the dial and I wouldn't like to grip the dial in any kind of movement holder if It could be avoided for fear of damaging it. Maybe I'm misunderstanding you?

      Balance spring fell out of regulator pin.

      By HectorLooi · Posted

      Hi Frank, you have dived headlong into the deep end. Hairspring work has to be the scariest thing a newbie has to tackle. Your hairspring appears to be bent and just putting it back into the regulator would not allow the balance to work properly. It might start oscillating but the performance would not be good. The proper thing to do is to unstud the hairspring, remove the hairspring from the balance, reinstall the hairspring on the stud carrier, reshape the endcurve and centre the collet to the balance jewel hole. This challenge would either make you or break you. Hope that you will be able to fix your watch. Welcome to the world of watchmaking.  Watch this video. It think it'll give you an idea of the task ahead. From your 1st photo, I think you have a etachron type stud. Let me see if I can find a video on how to remove it from the arm.

      Have read of the Tech Sheet attached on the balance section page 12. It may be bent but until you reposition it back in the regulator pins you'll never know. Cheers CJ 4R35B_4R36A.pdf

      Balance spring fell out of regulator pin.

      By Hawaiikook808 · Posted

      Aloha All, My Seiko 4R35B movement stopped working today. Upon closer inspection, it looks like the balance spring came out of the regulator pin. This is my first time working on a balance. Any advice on how to get this spring repositioned (back to normal)? I'm pretty sure that while adjusting the beat error on this movement, I must have turned the stud (I didn't even know they turned), and the spring eventually fell out.  Will the spring go back to even spacing when it's back in the pin, or does it look bent? Thanks, Frank
