wristwatches

World War I brought much suffering to human history, but it also brought us many indispensable inventions.

The Team Turquoise team developed a wristband called Doppel, which can change the mood of the wearer by providing a tactile beat to the wrist.

With this new technology, the risk of personal information leakage can be attributed to the fact that the device is connected to the internet in a comfortable manner.
