And the single chrono dial for my home time, I would need to start the chrono exactly 6 hours before...so in this case I would need to start it at 6pm US time before leaving...it is not really made for that but an interesting possibility with a two counte...
A member here suggested it to me - even my AD was sur[raised when I told him I could do this...again it is really meant for the chronograph though...hope that helps !
Also, regarding the 2 time zone trick, I turned it off last night but I guess we can leave the chrono on for several days or even a week without issues I am assuming?
