I purchased this watch from the official online store, but I have never taken it out of the box. I took it out of the box for the first time to take these photos. The band is not included. I originally listed it with a band, but I am relisting it without one this time. If you would like the belt as well, please let me know and we can discuss the price.

A hybrid movement that combines quartz with an automatic (mechanical) rotor. It boasts the same high accuracy as quartz, and it is a sustainable next-generation movement that can be used without worrying about battery replacement because charging is done by the rotation of the rotor. The rotor rotates with the movement of the arm and generates and stores electricity itself, so it can be charged in any environment. It has active functions such as 20 ATM water resistance and luminous paint, and also has a highly fashionable design that can be an accent to jacket styles. The tough and robust case design can be used as an all-rounder for everyday use and outdoor activities.
