Hi everyone, I have a doubt, currently for a GMT 2 Batman which movement do you recommend? vr3186 clean factory or dd3285 clean factory?

Thanks, Have the screw and rotor problems been resolved? I had read in this section that the dd3285 had these problems

The problems are solved. The screw and rotor problem as well as the lack of waterproofness no longer exist.

I would take the one who can get you a Batman. There seem to be delivery problems with some of the GMTs - Sprite, Pepsi and Batman.

Yes... on the DD3285 (and the VS3235) the balance endshake adjustment screw works. On the SH3285 (and the VR3235) the brass screw simply secures the balance bridge decoration plate.
Noob question 😅 what can I adjust with this screw? -/+ sec?
Thanks for the answer!

The brass screw on the dd3285 balance bridge is a Jack screw that allows you to raise or lower that end of the balance bridge. This allows you to adjust the “end shake” of the balance wheel. Basically how much extra space there is between the cap jewels and the ends of the balance wheel pivots. If I remember correctly it should be around 0.05mm (but I haven’t checked the manual so don’t quote me). Too little end shake and the amplitude will be low since the pivots won’t have enough room to run. Too much end shake and the balance wheel will jump around too much and will lose energy (low amplitude).

Thanks for long and detailed answer! The knowledge you have is amazing.

What power reserve is everyone getting here? Mine arrived a few days ago and it's been discharging after only about 18 hrs... (yes, have confirmed the movement is a DD3285)
