Hi all, I have a seiko Bell-Matic 4006a, ihad problems regulating it and when I put it on the timing machine it was all over the place. One minute it was - 80 secs next + 200 so I started taking it apart and found the problem to be a broken pivot on the escape wheel, there was just enough of the pivot left to hold it steadyish hence the Watch was running ok but just losing 3 mins a day. The problem is now I cannot find an escape wheel for this model. I have tried cousins obsolete, jules borel  obsolete  and contacted a few sellers on eBay, so does anyone know of where I might be able to source one short of buying a complete movement which would definitely not be cost effective. Thank you in advance.

See if you can move the upper and lower stones closer to get this one fit in between.

I broke one not too long ago, arbor on it was completely gone. Had to get a used one off of local shop for the price I am affraid to publicaly anounce.

According to ranfft ->  http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&Seiko_4006A

The balance is Balance staff Seiko 315470

These guys claim to have the balance staff -> https://vintageswatchparts.weebly.com/seiko-parts.html

Whether they actually do or not, I don't know, but you could give them a try.

Looking at the op’s post he needs an escape wheel not a balance mate

Hi,

speedtimerkollektion.com seem to have several 4006 watches/movements for spares/repair. Not cheap though....

They also show many parts but not escape wheel . Might still be worth asking....

The p/n is 251805 acc. To the data sheet from Cousins. Might be worth checking other sheets to see if the p/n is used in some other Seiko movement.

I had thought of that but it was going to be a last resort option, I have now managed to get one thankfully.

it is seiko part# 251805.....below is a link to parts list and manual for the 4006

https://watchguy.co.uk/technical/Seiko/4006A.pdf 

I found one on ebay NOS $21 with shipping

https://www.ebay.com/itm/SEIKO-Escape-Wheel-Pinion-Mechanical-Watch-251-Part-Japan-Made-NOS/303066393666?hash=item46902a2c42:m:m0LlX7sqVJ04bDwEXo-OtUw&frcectupt=true

I think I had gone escape wheel blind, I had looked at this listing and did not see his drop down list. Thankyou, I have now ordered the 251805.

      An intro…

      By HorologyHead · Posted

      RichardHarris123: Hello and welcome from Leeds, England.  I have family all over Australia, went as £10 poms Thanks Richard. Hope you’re able to visit your family here and that they’ve all done well 🙂 My relatives arrived from England in the 1790s transported on the ‘Second & Third Fleets’—a story of timber sailing ships, of convicts and doing well in this huge Country of Australia. When I visited the UK in the 1980s, I was too young to comprehend the depth and breadth of its history…  Best wishes, Mike William Chapman, my 4th great Grandad’s charges, at age 23 read at the Old Bailey; sentenced to 7 years of transportation to Sydney.

      New balance staff not riveting to balance

      The whole process and the progress are closely observed, it's hand-driven and very controlled. I can't see the "danger", unless you are watching the TV while doing it. As you could have read, and in this quote "wheel" is the balance-wheel.

      Have you got the pallet fork installed in the movement when you see the train move when using the setting works? As nevenbekriev said, without the pallet fork to lock the train, the behaviour you are describing is normal. If this is happening with the pallet fork installed, you have a problem in the gear train, it should be immobile when the pallet fork is locking the escape wheel.  The fit of the circlip above the pinions on that wheel is crooked in your pictures, it should sit flat up against the upper pinion as in Marc’s picture.  Hope that helps, Mark

      Stem broken - can it be rescued?

      By Khan · Posted

      Hi I got a Jaeger LeCoultre K911 movement, where one of the stems was broken. Part no. Should be 401.  Im based in Europe and tried Cousins but its discontinued. They except to get stem in stock for cal. K916 but will that work? Or Is there a way out to join the ends?

      The part was how it fell out of the movement - the train wheel bridge wasn’t screwed in.    I’ll probably dismantle the part, if I can, to work it out.    The train of wheels ran fine - it was only once the keyless works were installed I noticed the problem.
