Chapeau! Well done!
It is not easy to adjust timezone while traveling…
If you can add a pointer 0/3/6/9 oclock on inner rotate ring. That would be help for timezone.
PS. Thanks for your great clock face. I’ve done some modify and fix angle by my opinion on earth “spindle” from day to night. Now it becomes a good Timezone watch.
What globe and city ring are you using? Mine works just fine. Just switch out the provided globes and rings, easy. Make sure your globes and city rings match. It sounds like you adjusted the pre loaded bangkok ring and globe. Where are you located?
