I acquired this movement recently and upon disassembly the spacer between dial and movement. Cracking was observed. My question is because I've had this happen before " is this common to this movement with age ie does this become brittle" Or have I just been unlucky ?

The example shown was fitted with a 7s26 dial that somebody had managed to fit. One of the dial feet appeared to be bent to accommodate this.

When I lifted the dial the bent foot remained in the movement and yes I did position the eccentric cam first.6a9c3f11ea0bf5827cbaf7a096d3b211.jpg

Very common unfortunately? Had they been worked on and fitted with an other dial.
Probably have a few if you need? 

Im sure I have a spare dial for this somewhere. I'm not sure what I want to do with this movement. My timegrapher indicates wear. Low amplitude and a scatter pattern when not in the dial up or down position , so something in the escapement is touching. Hairspring looks good and not touching anything.
Movement fitted with a 7s26 rotar as well which is good (gold dust)
Think I'm going to keep it for parts. It's seen better days.
Many thanks though

The same spacer is used in many older Seiko movements and they do have a propensity for cracking. You can still use them as long as it has only one crack in it and the spacer is still in one piece but if it bothers you nos ones can be found on ebay.

First : How do you know if the spacer is cracked ? the watch you see is my avatar . second : i have it since 3 or five years , i can't say realy but my " 5 " is in working condition.  However, when i received a movement ( 6119C for another old Seiko 5 ) i 've never seen a spacer on it . Is it just on a 7009A ? because it's the movement that i have on my watch and at this day, no problems at all...

I can't really say what particular other movements employ this spacer or to be probably more correct "A 2 piece movement holder"
I do know the later 7s26 movements employ a single movement ring and the dial fits into this as opposed to the movement itself. In my opinion a much improved design.
If on your 5 you remove the movement from the case, you will be able to remove the first movement ring from the rear.
Then you will see the second ring lodged between the movement and the dial. It's function is to allow enough space for the complications to work freely and not jam.
Careful examination even with some magnification, you will see faint crack lines on the spacer.
Hope this answers your question

While Seiko spacers do crack, it is usually because of improper handling and being glued to the movement/dial due to broken dial feet.

Citizen plastic spacers on the other hand.... this 'clicks' positively onto the movement and need to be bent a bit to get them off.. result.. broken spacer. It also takes me a while to figure out the correct way to fit it back. You can mark it near the stem to help you but that's for beginners (ohh alright .. I usually forget!!).

-digginstony, If I may ask, was this from India?

The movement was acquired from a car boot sale in a poor state for £10. I do have a couple of other 7009A movements and 1 being in good condition but I lost the day jumper spring when servicing!
So I will exchange the spring from this movement (and be more careful)
Also the rotar is very good so I'm very happy with the purchase.

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.

      I did not. I thought about it, but I had cleaned it in my ultrasonic, and the tech sheet shows lubricating it in place already assembled, so I figured discretion was the better part of valor. Although since I have to depth the jewels anyway, maybe I pull the pinion off to rule it out 100% as part of the problem. Do you know if there's a safe way to do it? I don't want to use a puller because it would push down on the plane of the wheel, and that seems like a Bad Idea. I thought about using a roller table remover, but I don't think I have a hole stake pointy enough to push it down.
