Sure. Just checked. When the crown is rolled forward in GMT mode, the hour hand jumps BACKWARDS not forward.
On my Rep 960 with hour jump function advances an hour when I roll the crown forwards. Not sure if all the rep movements are like this or not.
Thanks bro.
Rep movements can differ depending on movement.
For hour jumping in crown position 2:
True clone Rolex GMTs
VR3185, SH3186 - fwd crown = forward jump
SA3285 (new GMF) - fwd crown = backward jump
ETA and (most) DG3804s GMT
2824 CHS timebomb - fwd crown = backward jump
2836 and 3804 ICHS - n/a, the GMT hand jumps
