This simple and small clock can easily be adjusted when you are traveling. The world clock is design by Masafumi Ishikawa. It can be adjusted by rolling it using one hand. The hourly hand will easily adjust itself depending on the marked time zones that is written on top. It uses a one hand marker which indicates the hours and minutes. It uses a quartz movement that is run by batteries inside. It comes in three colors, black or white or wood and each color will have a contrasting hourly hand color. It is now available for $59.
I like the design of this clock. Not only that, the concept is well executed. Just by rolling the clock, it will easily adjust itself on the current time zone. We need more of this.
