Constantly traveling the world, the Ticwatch makes it easy to see the local time reliably and quickly. It would be extremely helpful, however, to have a watch face with more than one time zone option: for instance a local time automatically synced with my phone and a "home" time zone so we can always know the time at home. Even three times, including a Zulu time would be very convenient.
I also found a glitch where it won't update the time correctly after a long flight unless I change watch faces. This is frustrating and it used to work correctly when I first got the watch, but has since developed this glitch.
