I purchased the ZF bb gmt from pure time in November Qi looked ok but I think the bezel is slightly off and I emailed them when I received in mail. No reply. Also I’m not sure about the gmt function. I set The red gmt hand 5 hours behind the hour hand and every hour advanced only advances the gmt hand by half what it should be to track the 5 hour difference. Maybe I’m setting it wrong. Can someone send a video demonstrating so I can compare to what I’m doing. Thanks,

GMT hands advances half for every turn of the minute. That is correct. But your bezel is definitely off. FYI should be 4 clicks every 5 minutes. Mine is just slightly off when clicked to the 12 marker.
To set the GMT. Pull the crown out fully to adjust the hour and minute hands to 12 o'clock. Then push back to the first click and turn the crown counter-clockwise to adjust the GMT hand to go to the 12 hour marker. Then you are set. Pull out the crown fully and adjust your hour and minute hands accordingly. To adjust date turn the crown clockwise at the first click when pulling the crown out.
I find getting good working bezel is difficult from just looking at QC pictures as you can't tell any flaws in the bezel until you get it in your hand. So lesson learned from buying the first bezel watch that is misaligned or loose to making sure you ask to check it before its approved. This is what I am going to be doing in the future.
