This small and minimalist timepiece by Korean studio Elevenplus encompasses 24 different timezones in its body. The trick is in the cylinder that allows you to view and switch between geographic locations in a single intuitive motion. Simply rotate the clock to put the desired timezone on top, and you will have the correct time.
The designers explain:
Let’s say someone living in New York wants to know the time in London. When it is 5:57 pm in New York, you can see that is is 10:57 pm in London if you roll the clock so that London appears on top. See the number on the clock to read the hour and the position of the minute hand to read the minutes.
The hands of this world clock move independently from the rest of its body, so they quickly transition to any timezone. The piece comes in three colors: gray, blue and orange. Check out the video to see the clock in action.
