Seiko 6106 Movement "in Loving Memory"


Recommended Posts

Service of a Seiko 6106 Movement



Sorry I have been slack posting movements I've serviced at home, but work has been busy, and the movements I've been servicing are not that different than what I've already posted ... just more of the same.

Well, I got another one of my Mum's friends who asked if I could repair their watch that was given to him on his wedding day by his wife: who has now sadly passed away :(

Of course I said YES!!  And it turned out to be a lovely old Seiko; but a little worse for wear :unsure:


The hands had fallen off, and the plexiglass was so scratched you could hardly read the dial.



After opening up the caseback, there was evidence of corrosion starting to set in ... but thankfully it was caught in time.



Here's what the intact movement looks like.



Once the automatic works were removed, it was obvious this poor old thing has never seen a service since it was purchased in 1974.  Very dirty, and very dry.



This movement has a complex keyless works which included a pusher for rapid date change, so before I started removing the dial side, I pulled the Balance and Pallet Fork ... just to be sure to be sure :)

Notice how dirty the movement is from this angle as well.



Ok, on to the dial side, to remove the calendar work and the Keyless work.



Calendar work is pretty much like all Seiko's ... minus that annoying phillipshead screw, thank the Lord!



Here's a picture of the Keyless work, with the incorporated pusher system for date change.



More of a close-up of the pusher arm



There is also a large spring for the pusher mechanism



Once that was all disassembled, it was back to the Train Gears and Mainspring.

Notice this movement also has a hack that stops the Train Gears; instead of the Balance ... all very interesting :)



And for my good mate Bob ... here's the picie of the Automatic work mate :P

Look how dirty and nasty the Eccentric Bearing is ... Ewwwww!



Here she is coming back together after a long bath in the suds

Lookin much better!



I polished the case, and spent about 15mins with Ploywatch trying to polishing all the scratches out of the glass ... but it was just too far gone :(

Still at least you can read the Dial now :P



Off to the Timegrapher and in typical Seiko fashion, once cleaned it purrs :D



Hope you enjoyed this post, and I'll try to post more often guys.

Good to here from you again Lawson, especially with another well illustrated post. I'm really glad that work is going well for you!

Excellent post as always Lawson, me too am glad work keeps you busy and in heaven! We were already missing you!


Thank you for showing me the automatic assembly...and the excellent pictures of the whole process! I believe this is one of the most outstanding results -- as seen in the time grapher -- considering the age of the movement. As a coincidence, I ordered a bunch of those from Ramon in ebay and will soon be following track, trying to make work some of them.


As a side note, since they are not runners and some have an issue with the hairspring (missing, broken, twisted, etc) I was wondering if there is a way to find an equivalent hairspring to fit in the balance wheel and how to go about ordering it. If you have any information -- or any other member reading this -- on the subject/process/how to, please let me know or create a new link. it will be deeply appreciated.

Nice one Lawson, very well presented as always.




Good idea about the hairspring, although I will have to get yet more kit to fit one. I have a 6106-8240 in grade A nick & a 6106-5410 (my Dads old watch) with balance issues. Managed to track down a second hand balance (no NOS to be had) but was still being a git & has been on the back burner for a while. The balance is listed as part No. 310.611 but I am informed that 310.614 will fit, Stefan AKA scillachi61 on fleabay has some  & have just ordered one(not cheap unfortunately, but that's the price of hens teeth). Will let you know how it works in due course.

Hey Bob,


For Seiko spare parts I use "speedtimerkollektion" on fleabay.  His prices are very reasonable, and if he doesn't have the Seiko part you need listed, just send him a PM in ebay and he normally has it in stock.


Hope that helps my old friend :)

Fantastic post Lawson, and excellent work on the Seiko. What oil/grease do you use for the autowinder?




My oils at home are a little limited ... D5, 9010, 9501, 8200, 9415, and silicon grease.


This is what I used ...

On the Eccentric Bearing - D5

On the jewel for the Pawl Arms - D5

On the Pawl Gear pivots - 9010


It seems to have done the trick quite nicely.

Also if anyone is wondering why there is a rub mark around the outer edge of the Base Plate and the Mainspring Housing, that is the sign of an Eccentric Bearing failure.  It's still working in this particular watch, but it's being to foul and will have to be replaced ASAP.




Just thought I'd add that little note to help others in their fault finding.

Didnt realise that hacking is also found on 6106.

Thoughts only on the 6105B.


that is why this is such a great movement. i have 7 of them and can't get enough. now, i only wish it was a hand winder, too.

      Hi All
      Any ideas how I can improve the look of this calendar ring?
      The staining seems to have got underneath the lacquer.  I've not tried anything yet as I'm a little hesitant at using any liquid on it for fear of damaging the lacquer further.  i'm still learning...
      Many thanks

      I've tried to service a tiny Seiko 2601 Automatic movement very small for me (18 mm)
      So I finished  yesterday all was ok I've rewinded and I was happy because the balance started I've not checked amplitude or precision (for me just ticking it's already something)
      Today I check and the watch have stopped and do not restart even when I rewind manually. 
      Now when I put the main spring back in the barrel I've broken the end part at the opposite side of the pinion it was like a V because I don't have a main  spring rewinder so I make it manually (Shame on me).
      So I suspect that the main spring is not clamped in the barrel and it's just spinning inside without giving any power to the movement.
      The question is what method can I use to check my assumption. Not forget It's an automatic movement.

      Good day all,
      I'm a recent 30 year retiree and elected to start cleaning some of my older watches that ended up in a box wrapped in a towel.  One in particular, a gift from my grandfather, began working with a new battery but the crystal appears foggy.
      I would appreciate specific instructions for removing the stem/ crown and cleaning the crystal from an 1980 Seiko with the 6030A movement.
      Thank you in advance.

      I recently purchased what I call a “Franken-watch” Seiko from a seller on eBay from India. As I’m sure many of you know by now there are hundreds of listings (see screenshot below) for cheap Seiko watches with weird dials, most likely repainted. They aren’t fully “fake” as most of them come with genuine Seiko movements. My Retro Watches has a good video where he looks at a watch he bought from a dealer similar to this if you’re curious, see link below.
      Anyways I thought one of these cheap weird watches would be a fun one to play around with as my first project, and I paid $20CAD for mine which I thought to be good especially if the movement inside was genuine Seiko. First problem I noticed was the bracelet (which was cheap and terrible) was held in by shoulder-less spring bars which would be fine if the lugs had holes but they do not so I had to saw the bracelet off so I could put another one on (see wreckage below). There’s more but I won’t bore you too much..
      The watch came with a Seiko 6349A (23J) movement which is a variation of the Seiko 6309 (17J) movement. The movement was held into the case only by the crown (see pictures below) and didn’t have a movement ring. As I understand this is bad because the movement isn’t securely held in the case by anything. I’ve tried to find one on eBay but I’ve had no luck, and I can’t find anywhere that has the ring size so I can’t try and find an aftermarket one. 
      Does anyone know where I can get one of these movement holder rings? Is it even possible to get one off of CousinsUK or Esslinger or somewhere? Do any of you have one I could buy? I am very stuck and any help is greatly appreciated!

      Can someone please explain to me how on earth do i unwind this Seiko 5126A movement prior to reassembly? (Picture attached).
      No manual winding as far as I could find and the winding screw on top of the bridge is not counterturning automatically when I push back the click and basically nothing happens. I can unscrew it but this just releases the screw.
      I'll mention that I did experimented with this movement (it's my watch) and first time accidently removed the bridge with power still left. No visible harm was found and after reassembly (hopefully a proper one) everything seemed in order (except for the oiling and cleaning which I haven't yet performed and is due now).
