There is a spring putting upward pressure on the seconds pinion but the click is going on top of the bridge so it is t installed yet. I’ll try the tapping method. The week end is coming so I’ll spend time on it

Bridge and more reinstalled. 

 

 

it lives!  But the timegrapher says it is not in very good health.

And here the movement reassembled. 
You can actually see that I still do not have complete control over my microscope camera, but I can project on a monitor and I end up taking pictures and video of the monitor. Somehow the camera doesn’t seem to like the SD card that I bought for it.
Last bit that will be for tomorrow is figuring out how to put it back in the case.

Somehow,  I also think that the title for this topic is completely incorrect. 
 

It shouldn’t say service it should say disassembly and reassembly.

The reason being that the movement is worse off after than before. However, I am still happy that I managed to completely disassemble it clean it not lose anything reassemble it. 
I was really confused about the lubrication because the Miyota tech sheet recommends something completely different from what I am used to. Places where are I expected oil show grease. And vice versa maybe I am misreading the legend. Anyway, I probably put the wrong lubrication in the wrong place, but I still got to practice grabbing tiny drops of oils and putting them precisely where I wanted  

I’ll call this one a success

Slow motion video from my phone. Hard to see anything except maybe the amplitude which looks pretty bad to me. 

Also a couple of pictures trying to show the spring without removing the balance from the cock. They are also pretty hard to read sorry about that

Just my 2 cents: It might be because of the angle the photograph was taken, but the exit bend and the windings don't seem to be evenly spaced. Was it properly demagnetized? If you mount the balance complete on the plate and (while the watch is not running) you move the regulator arm, does that effect the spacing of the windings? It shouldn't. If it needs adjusting, the best way to see what needs to be done to it, is removing the hairspring and place it on the balance cock. Is it centered, is the exit bend ok, etc.

Yes it has been demagnetized and I agree that the pictures don’t show much. I’ll eventually detach the hairspring from the regulator to take a look.  But my previous experience doing that with another movement wasn’t. Very successful meaning that I am not quite delicate enough with my tweezers to detach and reattach the hairspring without damaging it.

      Looking to try servicing an old movement

      By Neverenoughwatches · Posted

      I'm in the " crack on with what you have " camp. Since you are in the Uk Ingersolls are plentiful, mostly the Great Britain models, but the Swiss made ones are still fairly common on Ebay. The New Chinese clones, were difficult to get parts for...🤔....I'm not sure if they still are, the quality wasn't that great either when it came to things like shock springs. Another complete watch same model Ingersoll will probably set you back less that a couple of clone parts that you will almost certainly lose or break. I never took apart a new working movement, I don't believe it held back my learning at all, in fact quite the opposite.

      Vintage Seiko lume pip technique

      Yeah I can't take credit there - I thought the plastic punch thing was a work of genius when I first discovered it!

      Vintage Seiko lume pip technique

      By tIB · Posted

      Since I've learned lots here I thought I'd share a tip I picked up elsewhere and put to the test... For that 6105/6309 bezel lume pip look I've punched a clear plastic bottle of water, sanded it for the frost effect, removed the (smaller) pip from a standard/cheap replacement bezel, drilled it out to 2.5mm and fitted it using a smaller punch - fresh lume to hold into place.  Pressing into place is a bit awkward but you soon get the hang of it, and the end result is pretty decent I'd say... The worst part probably being the drilling rather than the pip!      It started out like this:

      Seiko 6105 crown gasket service

      By tIB · Posted

      Ive asked this at a Seiko forum but I know there's plenty of experience here too...   As I have it the recently discovered servicing technique on these is that you stuff the crown full of gaskets and work it until the recessed washer pops, remove the washer, switch the gasket out, dish the washer and push it back into place, levelling out the washer in the process? First attempt did not go to plan... I tried using a plastic pusher to manipulate the gaskets in the crown... Wasn't strong enough and I was struggling to even get the gaskets in up until it broke.   Rethink consists of making/using actual tools: I don't have a staking set, so I've got the old man fashioning a metal pusher, essentially a 2.45mm OD tube with 1.6mm ID with a 6mm press the other end. Also got him on a dishing block/conical stake (sorry I'm terrible with terms) and a holder for the crown while I'm working on it...   I figure that's enough to do the process described above? Push with the metal pusher, dish the washer with the conical stake, press back in with wider flat press (drilled centre so it doesn't catch on the tap).    Plan is to stuff, press by hand and repeat? If that doesn't work by hand I've a drill press I could attach the pusher to for a little more leverage if needed. (Obviously I don't want to go too mad with that, and hopefully can avoid it altogether...)   Sounds like a plan? I'd welcome any advice here, since I really don't want to wreck a crown. Having replaced all the other seals though id really like to sort these too. I welcome any input/advice from those who have been there and done it... Thanks!
