Well, I thought WHS 2836-2 were good....but mine had a problem just popping in-out the stem.
Before, it was working brilliantly! Then, I removed the stem, popped in back again and....what?
The GMT hand isn't moving! Stuck! (when following the hours hand)
If I set it backwards, it moves; Then if I try to set the time, it got stucked again.
I won't buy (touch) a chinese mod anymore.
My advice would be to find someone who's brave enough to service this kind of mod.
Swapping with another 2836-2 could be expensive: does the watch worth it?
Is it a noob gmt? gen parts?
