From How do I change the time on my Fitbit device?
How do I change to a 12 or 24 hour clock?
Note it must be done from fitbit.com dashboard; i.e. in a web browser.
Best AnswerThanks for the reply, how do you sync through fitbit.com on-line ? I can't see where I do that. Thanks again
Best AnswerAfter you have requested the changes at fitbit.com and said Submit, then you can do regular sync from phone app or wherever. I see how that was misleading. After you have done the Submit, the change is in your account, so a regular sync will pick it up.
