[rs1984]

My friend gave me the parts of a broken movement, is this the right one to convert the movement in a GMT?

Yes indeed, that should do it. Don't forget you need some new hands.

Okay great, i need a new hour und gmt hand or completely new hands. On alix the most hands is for nh34 and nh35?
The GMT hand is 2mm or 1,8mm?

I found this hands for nh34 https://de.aliexpress.com/item/1005004966406707.html
but minute hand is to short 12,5mm and i think not so thick like the original i need 13mm.
This is because the ex2 is 42mm.

You can use the hour hand from NH34 /35 but not the GMT hand.

GMT hands hole sizes
2824 1.5mm
ETA 2893 1.8mm
DG3804 2.0mm
2836 2.0mm
NH34 ~2.15mm (haven't measured but it's HUGE, way too big to crimp/modify to fit on 2836)

Here is a set for DG3804

Maybe I can modify the gmt hand 1,8mm to fit in 2mm. Is the hour hand of dg3804 the same 1,5mm?
Or is it possible to buy a complete new set from TD? I think the quality would be better.

you really are a big help, thank you again

Hah, I posted the DG3804 GMT hole size wrong. It is in fact the same as 2836, at 2.0mm (previous post corrected).

The DG3804 hour hand will work also, it's (nominally) 1.50mm

The minute and second hands can be made to work with crimping (decreasing) and broaching (increasing) their hole sizes, though this is an advanced modder technique.

Be aware that most cheaper aftermarket hands will have green lume, not blue-green like TDs provide. Reluming is an option if you can't tolerate different color lume.

Neither the CHS or ICHS ETA versions of your model are still available so you won't get hands from a TD.

When people talk about modifying hands for fitting other movements, I am still impressend and it reminds me how much skills it takes to be a true watchmaker.
