Possible to repair a damaged date wheel?

[tIB]

Assuming that's the issue, is it possible to repair a date wheel if it's jamming because teeth are bent rather than worn away? Is this something that actually happens or is my guess off the mark?! Thanks!

Can you post photos of the bent teeth?

I will when I get it off the watch - I'm assuming that's the issue rather than knowing it is, hence my last question... all I've got to go on so far is that it's jamming at the date change on some dates and not others.

It depends if it's metal or plastic.

It's metal - from a Seiko 6106.

I expect they're bent up so should be able to bend them back with a pair of small pliers.

Thanks very much - I'll have a closer look on Thursday hopefully...

Here's the date wheel - hard to photograph really but I think I see a few that are bent upwards at the tip... Any advice on rebending?

Difficult to see from the photo but it does look like a couple could be worn.

If they're bent then it depends how they're bent if you can straighten
them with pliers and/or tap them with a drift on a metal block.

I wondered about wearing to a few of them - I had a go at straightening out but I'm not sure I've succeeded; looks better but hard to know, and possibly wear anyway...

Shame really as finding the correct date wheel for a 4o'clock 6106 date wheel isn't going to be cheap, given it's also the 6195 date wheel. 

I'll keep my fingers crossed but don't hold out too much hope...

[AndyGSi]

Yes, even the standard Black White 801610 aren't cheap.

The Black Gilt are a bit cheaper but then the Black Silver are dearer still.

I'll have a look tonight but I think all my spare movements have pretty ropy disks.

Edit

Just realised I've got an 801602 listed in my spares but don't know if it's NOS or used.

I managed to get a black/gilt 801612 last year pretty cheap - think that one you have might be for a quartz movement? Thanks for checking btw. 

Some good news though - it's actually passed my first test: passed through date change on the tenth without issue. I'll try the 9th next...

[AndyGSi]

The 801602 is the correct disk.

Ah right, sorry hadn't realised it the 610/612 were replacements. 

So it's now been through three of the troublesome dates without issue uncased... I've cased it up to see what happens next - there is an anomaly there which is perhaps causing the issue...

So it failed on one of the two date changes I've tried case up...

Anomaly wise I noticed this has an incorrect plastic dial spacer (is that the term? Dial ring maybe?)... I wonder if that could be causing it to fail? 

More tests...

Not replacements, just alternatives

602 Silver

610 White

612 Gilt

Hmm... Might be ok here; I've tried it on over half of the dates by manually winding to five or so minutes before the date change and all but one have gone through. 

 

I guess I'm at the point where I'll wear it for a while and see what happens each night...

[tIB]

Well it's passed the first test... good start!

I've ordered the correct dial ring and movement holder since the dial doesn't sit flush against the case on one side.

(I'll need to find that spring that clips into it - any ideas for a cheap source?)  

I'll continue to run/monitor and will fit those when they arrive. More hopeful that between cleaning, bending and refitting things I might be in luck...

Bent or worn or both you need a new one.

I know you're right, but really I was just trying to get this back together and running in order to have it back in one piece and move on... It's one of those where I bought it as a donor but am trying to put back to right.

It's a nice watch though and predictably I am getting quite attached... We'll see...

Ooh, have found a reasonably priced NOS  gilt wheel from the guy I bought my last one from. Gilt not ideal given silver dial but probably better than a worn/bent one...

Make sure you lubricated the teeth and the indexing spring once you get the new one.

Ooh, didn't know that - what should it be lubricated with?

What makes you think this?

Strange how the Service Manual doesn't mention it.

I use a synthetic grease like 9504. It gives a noticeably sharper snap when the date changes.

[tIB]

Day two - still going! It wasn't passing days at all previously so perhaps the date disc isn't as bad as feared (or Ive hit the good parts of it?!). 

 

Hmmm, closer look shows the day is a bit out of line after last night's change... Not sure what's happening there?

I always lubricate the date wheel teeth. I think it was mentioned in an Omega document I was working on, and I have done it ever since. It makes the date click over much smoother, and to me, it makes sense since it's such a high wear area.
