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:Screenshot_20241001-2054402.thumb.png.9acc1fb1acf2f2ab4b05c527a2b3a390.png

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.

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. IMG_20241001_193506.thumb.jpg.a68da17ac5bd6cbe103b67d7bda517da.jpg...

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…

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...

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...

    • Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with. I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements.  Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!
    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
