Good evening!

have been working on this Seiko Pogue with 6139B, for some time now. There was multiple changes in broken bridge screws and bad 888612. So went down eBay and resource those items.

Now when everything arrived, put it finally together and to my surprise chronograph resets quite nice, but not to 0. More specifically it resets to 12s. This end of pivot is D shaped as well as hand. With my strongest loupe I see that flat of D is facing this 12 minutes marker too. 
 

Did anybody met with misaligned center wheel like this? What is potential to fix this (I mean, these are not cheap to get).

Cheers,

Jakub

Hi there Jakub, this is a common problem and fixable .You can either source another seconds hand which will be aftermarket and i'm guessing you don't want to do that , or what you need to do is purchase a hand setting movement holder like this one https://www.ebay.com.au/itm/VTA-S-501-Handsetting-Tool-for-SEIKO-6138-6139-2020-VERSION-Orange-NEW/303671613901?hash=item46b43d19cd:g:VYAAAOSwdy1dymN1 

whilst setting the hand you push the reset button to center it at 12 o'clock ,however be very careful not to crack the seconds hand post . The reset button needs to be kept depressed when fitting these to hold the relevant wheels in the correct position.

 

Also have a read of this for 2nd approach https://thewatchbloke.co.uk/2016/11/04/seiko-61389-sweep-hand-issues/

Hi @Graziano! Honestly, you cheered me up a lot with your answer, thank you. Interesting that I couldn’t find anything about this on internet, maybe because I wouldn’t pay attention to topics about setting hands. As you recommend, the movement holder is ordered. For delivery reasons I’ve taken this one https://www.ebay.com/itm/193909107883 

It doesn’t look as good, but I believe it will do.

Cheers

Jakub

      Argh. Breaking pallet pivots

      By Nucejoe · Posted

      If a runner, I usually let the movement run in naphta for a minute, some movements need a bit of encouragement to run in liquids, so a quick dip of the movement in naphta then remove and encourage the oscilator with puffer, repeat several soaks.  Or if you don't want to soak or dip the movement in cleaning solution ,   keep putting naphta on jewel holes as the movement runs on bench. A pre-clean of some sort  helps.  Avoid lifting out the fork with tweezers or any tool.  Try blowing fork pivot out  with strong puff of air from jewels holes back side. Good luck .

      60! Wow, that's a lot. Can't say I understand the problem because disassembly is usually quite uneventful, except for springs launching into space. Most people break pivots during assembly. I use a homemade brass pry tool to loosen parts. It's just a short length of hard brass wire sharpened to a chisel point. Don't pry at just one point and crowbar it out. Pry at the notch and when a crack opens up, slip the pry tool in and loosen it at a few more points until the bridge is free.

      Argh. Breaking pallet pivots

      By WpgRob · Posted

      Beginner here. Of about 60 watches I’ve serviced and repaired, I’ve broken a pallet pivot on three, always during disassembly, and usually when the old oil has transformed to glue. Each watch was Swiss, in case that makes a difference. Here’s what happened in each case: - unscrewed the pallet bridge or cock - gently inserted a screwdriver in the  slot under the pallet bridge or cock - gently but firmly rotated the screwdriver, avoiding a forwards force on the screwdriver. If alignment pins stick, the cam action is alternated back and forth between back corners of the plate. - heard a small but horrible click. Is there a special tool or technique for safely lifting the pallet bridge? Should everything be soaked in naphtha before beginning disassembly if there’s any sign of old oil gluing parts together? Thanks! Rob

      Full plate watch, Suitable tool for adjusting & testing pallet stones?

      You shared this test with me a few months back on a Hamilton project and so I had checked this watch to find the pins were still equally spaced. Their screw slots were undamaged and very tight hard to move so maybe no one has messed with them before. I can't work on it much today but I did measure the fork slot again and it seems like 0.44 is the right size. I measure the jewel that had been installed at just 0.42. would an undersized too narrow impulse jewel impact the impulse drastically? I ask because I have had it at a state where flipping the fork manually with a tool would unlock some of the time, but the balance was never capable of unlocking.

      Help with repairing a quartz clock

      This was what I was afraid of. The movement is not one of the generic black square modules. Remove the movement from the clock and try prying it open very carefully, without breaking the plastic tabs. The plastic might be brittle from age. Clean the wheels and check the battery contacts for corrosion. Check the PCB for bad solder joints. Take plenty of photos along the way.
