Hi guys,

I need to find a complete balance  or just the hairspring but I am unable to find something on the internet. 

There are two marks on the dial side of the plate: AS and a number 43. I cannot find the AS movement number 43 (maybe it is not a type of movement). 

All your help would be very appreciate it. 

Thanks

Sure is a AS movement. But haven't seen exactly that. Don't think the 43 has anything to do with it. have you looked on ranfft pages? What is the diameter of the movement? I have a box full of mostly AS movements . But don't think i have seen that keyless work. Some of the bridges looks like AS984

Thank you Rogart. 

My watchmaker thinks the same as you. He is retired now so he has a lot of experience but he cannot find on the books this movement exactly. I talked to him this morning and asked for the number below the balance bridge but he said there is no number! Could it be because this trench watch is from 1914-18?

He told me too that the diameter is 10-11 lines, just in case it helps you.

Hope you may help me with this info. 

 

Thank you a lot. I’m gonna see on the internet the AS984.

Hard to find info on this old movements. Have a bunch of AS movement that just says AS on the dial side and nothing else. I thought i seen it somewhere. Take a look on this page. There is a AS 168 that has the same kind of click spring. So something close to that is probably right?

 In case you didn,t find the right hairspring, hairsprings can be shortend to produce the right beat.

Is any h/s left on the collet? 

The collet size?   Picture of the collet helps.

      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!
