After I modded My WM9 V2 Sub with a gen Crystal,Tube and Crown and for shure a gen Insert
the Datenummbers [censored] me of a bit....
I had a gen Datewheel laying around so I asked my self can it be installed on this tiny movement?
The answer is YES
So what is need to do......
First you must grind down the gen Datewheel a lot to become it much thinner.....
Gen Datewheel
Grinded down a lot
Ok thats enough....
Here is the WM9 movement include Dial etc....
Now deinstall the Hands, I cover the Dial to avoid damages...
After that deinstall the Dial than it looks like this
You can see the movement is a Day Date movement like the 2836-2 only much smaller
Now the old datewheel must extracted from the movement
here it is
Here you can see how small the Datewheel on this movement is
On this small Area the Datewheel must reglued....
Now the gen Date wheel must glued and alligned on the movement
this is not an easy job believe me,it took me some hours to get it right
As you can see I marked the middle of the date on the movement holder...
This is how it looks good alligned
Now all the same way back
here is the Dial and Hand installed
And now my WM9 has also a gen Datewheel
Looks good in my opinion
Hope this small Tutorial helps some selfmakers ,good luck
