Seiko 7009A

[digginstony]

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.

Its common problem in these seiko watches , specialy in old ones this plastic ring cracks in pieces too easy

They must have been using poor materials, Seiko spacers since the last 20 years do not deteriorate.

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

Ok , no problem . i will see it when i'll send my watch for a ' clean and lube ' to a watchmaker or jeweler.. and i will ask him if the spacer was cracked . thanks for your reply .

Here are a few different spacers? Grey is 6119,6306,6309. And the white is a 7005,7009 . Black is 7S26.

A very good way to make spacers should be with a 3D printer.

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.
