If you are a practical person or busy person no time to adjust time, this is the one all you need.
Equipped with 'Multi Band 5' for atomic clock synchlonization in Japan, Europe, and North America, you can keep accurate time down to a second automatically all the time.
Moreover, every information (year, month, date, day, and second) you need from a watch can be seen at once with bolder digits in larger display.
This is the ultimate time keeping tool with coolness of retro-futuristic looking.
*Since this is Japanese distrubution model, the instruction manual or booklet is in Japanese only.
If you need those in English, I will provide downloadable URL.
