People who take a plane to go abroad usually need to adjust to the time difference. They also need to adjust their watches, mobile phones and other devices to the local time when they arrive in another country. Countries that are far away will have time differences. If you travel abroad frequently or need to deal with people from many countries, it is necessary to understand the time difference issues of various countries because if it's daytime for you but midnight for the other party, you won't be able to contact them. For these people, you can consider using such a globe watch. Instead of needles, there is a small globe inside the dial. This watch can display hours and minutes. From the top view of the globe, you can know the time in any part of the world. You can even take out the core of the watch and use it as an alarm clock. From the display screen to the front cover of the instrument, every part of the watch works together to show the time where you are and the time in any other place.
