Hi everyone,

I've been stripping/cleaning/reassembling a Seiko 6309A movement.

I'm new to this, so mistakes were made. During reassembly one of the stones on the pallet fork has detached.

This leaves me in an awkward position, as I doubt I have the skill to re-attach it and according to cousins, this fork is obsolete.

I've seen replacement forks from abroad on eBay, but they are expensive. Does anyone know where I could get one in the UK?

Thanks!

Thanks. Looks like this site has the part, but do I see it right that it's  €11,95 postage to the UK?

Read below: "Small orders below 25 euro can be send by regular mail (€ 2,95). It takes longer!"

I can vouch for speedtimerkollection, used him many times and no hassle. For clarity I’m not involved in any way, just a happy customer.

Ps: you could always learn to fix it yourself?

Or keep scouring the bay and you may find a movement you can cannibalise. But that movement may have unseen issues meaning you’d be back to looking. Or if you’re like me it’d just mean you have two movements you want to fix instead of one! [emoji23]

First and foremost lets figure out why did the stone come loose, how did you clean the movement and what solutions did you use?

gunna be almost impossible to find a NOS one if one is found it will cost about as much as a complete movement or even a complete watch will cost. So you have to make a choice on which route you wanna go. 

Keep in mind Seiko pallet forks are mostly interchangeable. off the top of my head a pallet fork from a 6106, 6119, 7002, 7009, will work as well and there are others.

Luckily someone on Facebook has offered to send me a spare! I can't believe my luck.

As for cleaning.... Bear in mind that I'm very new to this and I'm operating on the cheap until I know this is a hobby I want to pursue...

For most of the movement I used first a weak solution of dish detergent, then a wash in IPA alcohol, before a dip in a final uncontaminated pot of IPA. However, I did not clean the palette fork at all, because I read in a book that the adhesive used on the fork breaks down in solvents. (I also didn't clean the balance for fear of breaking it).

I know that ideally you'd use professional solutions and machines.

The stone actually came loose as I was re-fitting the bridge. The watch suddenly let all of it's power out in a great "whiiiiz". Perhaps I shouldn't have had power in the spring whilst fitting the escape bits?

Ah! That's good to know. I did look at a spare fork I have from a fake 7S26, but it was visibly smaller.

never had A pallet stone come loose in that manner. Could have had a bad cleaning previously. You def. cleaned it correctly by not using the IPA on the pallet and the balance. 

You should not have power in the spring until you have everything installed up to the pallet fork, in my case i dont wind it until the balance is installed. But either way none of this would have caused stone to come loose, so its anyone’s guess why it did. And Yes The 7s26 pallet is different.

I think what happened is that you fitted the pallet fork with a stone over a tooth, maybe even positioned its bridge, then wound the barrel, somehow the pallet was able to hold power for a while before the stone was dislodged while tighteining or being hit by the spinng escape wheel.

Personally I find fitting the fork pallet a very delicate task and have had some breakage while doing it, we aren't all born master watchmakers! One must be 100% sure that both pivots are in place before tightening the bridge, for that observe the stones correctly engaging teeth, and the bridge being level. Only then wind the barrel to try the fork flipping when slightly touched, which is a correct procedure. 

Regarding your cleaning procedure it is not necessary to use expensive solutions and machines (even if you can read some insisting advise to the contrary), but use of dishwasher soap for the movement is kind of unheard, better would be petreoum ether to dissolve old oils, followed by demineralized water, and then IPA.

      Hi to Blackminou29–am a collector/ caretaker—good luck to you following your repair course—with hindsight I wish I’d pursued a career in both watchmaker/ jeweler fields—good luck with whatever career passion you engage.   Thank you Watchweasol for posting the amazing TZIllustratedGlossary!

      Seiko 6601 Tech Sheet?

      By JohnR725 · Posted

      yes I noticed the new site and I miss the old site. It's the unfortunate problem of the Internet here today gone tomorrow sometimes some of the stuff gets backed up and sometimes well it does not then the problem with the early Seiko's were there were not necessarily designed for distribution across the planet and as such there is no customer support for them. So trying to find early stuff like technical information or sometimes even parts list for older Seiko is is problematic. But I did find you a you tube video. A quick look he seems to take a heck of a lot of time to actually get to the service single I did not watch all that but it does look like he did disassemble or started to say there's a tiny bit here

      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

      By Endeavor · Posted

      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.

      AS2063 - hand setting

      By Mercurial · Posted

      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
