6105a part ID and date wheel query

[tIB]

Landed a very clean looking 6105a movement today, though there's a plastic part in there that's sticking out like a sore thumb - see pic:

Has that had a plastic donor date driving wheel holder fitted from another movement? Is it an easy switch out? Anything I should note before attempting to change if I can find the original part? 

While I'm here any idea what other models date wheels will fit- 6109 perhaps? 6106 I'm pretty sure is the same? Annoyingly I think I have a 3oclock date wheel here and need a 4...

So the 6105A is a modified 6106A and the part fitted isn't correct.

Edit

Should have added.

What 6105 is it that has a Date @ 4?

Sorry, what I meant is that looking at the position of the teeth on the date wheel, it seems to have a date ring fitted that lines up with a crown at 3 (as opposed to 4 where it should be for these). 

Seems someone has probably switched some parts with a donor movement at some point.

I actually have a 6106 here with 4 o'clock date but while I feel I could probably manage a date wheel swap I'm not sure how much work is needed to change that date driver wheel holder (assuming that's what it is)? I'm a real novice when it comes to movement work. 

The movement itself looks good and seems to be running ok, though quite probably fast. Hmmm...

So the Date Ring looks OK to me.

Even though the Crown is at 4 the Date Window is still at 3 on both the 6105 & 6106 (Day & Date).

I thought the same until I mounted a dial and looked at the position of the teeth compared to a photo of the movement.

Here's how it looks - I assume that's a 6106 3 o'clock ring. While they both have 3 o clock windows the calendars rings are different - it's why the newer Seiko's all have 3.8 or 4.1 crowns I think. ...

I've never seen anything but a 3 o'clock window so expect it's something to do with the ring being out of position.

Your right about the window, but the position of the teeth on the date ring is different depending on crown position... It's slight different depending on whether crown position is at three or four. Hopefully you can pick that out in the following pics (it's close but different !)

…yes I encountered this. Bon chance trying to source the four o’clock ring. It took me three fails before I finally took a chance on a donor…

[AndyGSi]

Yes I see now and comparing it to this one for sale it looks like someone has also swapped the date dial

…how I was tripped up. EBay-ers posting the stock photo or parts list assuming the rings are the same. A nice email to Speedtimerkollection got the right part sorted for me…

The good news is I sort of have one - I hadn't planned on using my 6106 as a donor but since I've already stolen the crystal from it I guess there's a chance...

It's also whether I have the nerve to work on it... Like I said, novice on movement repairs but I have managed a date disc change before. Date driver wheel holder I'm not so sure about...

There is this gilt one at a reasonable price.

Edit

Just checked my stock and it appears the only 6106 I've got has a destroyed date dial.

check with the seller to make sure the photo is of the item for sale…

Some kind of equilibrium.

 

Did the date wheel swap, didn't try the date wheel cover as I got scared... 6105a movement reunited with knackered old 6105-8000 dial in Rdunae case (for now). 

 

Not too happy with the hands and the relume of a horrid relume took two goes. All working as should though...

Thanks for the heads-up on this one - I finally fitted it on the 6106a today after a bit of a switch around.
