PowerWatch 2 is equipped with a 1.2-inch color display, it is a smart watch that there is no need to connect to the power supply for charging. Speaking of Smart Watch, it really is a problem with battery exhaustion, Apple Watch needs about once a day if you have a good battery, you need to charge the cable about once a week with a cable. However, PowerWatch 2 has its own technology to generate from body temperature and solar power battery, so there is no need to detach the terminal from the arm and connect to the cable for charging.

PowerWatch 2 is made of aluminum case and strap made of rubber material, the case size is 42 mm smart watch. It is slightly more compact than the previous model PowerWatch, but the case size is 42 mm, so it is difficult to say that it is perfect for women and thin wrists. It actually looks like this.

The main body can generate power with sunlight and the wearer's body temperature, and the ring for solar power generation is arranged inside the bezel of the watch. According to the developer MATRIX, it is possible to store electric power from indoor or outdoor light.

The 1.2-inch liquid crystal color display installed in PowerWatch 2 is always lit but can be turned off. It combines a scratch resistant screen and a waterproof function up to 200 meters in depth, so it can withstand active outdoor activities well. The liquid crystal display seems to be looking good, compared with Pebble which is also a groundbreaking presence of smart watch, but it seems to be inferior compared to Wear OS and Apple Watch corresponding to touch screen.

The heart rate measurement function and the GPS function etc. are also installed in Smart Watch such as Apple Watch, but PowerWatch 2 says that there is a special function different from these. It is a function that lets you know how the user's body temperature has changed, and it is a function that makes it possible only by PowerWatch 2 constantly measuring user's temperature information for power generation.

PowerWatch 2 can not download third party applications like Apple Watch, but it seems that you can display all notifications such as phone, email, SNS etc. The developer MATRIX is the target of PowerWatch 2 as "outdoor user", and it is said that people who feel troublesome carrying around extra charger for smart watch is target. In addition, since PowerWatch 2 supports both a dedicated fitness application and Apple's HomeKit and Google Fit of Android, "The Verge is positioned as a rugged fitness tracker that does not require charging" and foreign media.

Digital Trends that the prototype of PowerWatch 2 was used has become a problem in the previous model due to the reduced sense of size and light comfort, and the installation of a solar battery "(the amount of electricity generation is too small) It is said that it succeeded in solving the problem that "does not move".

In addition, PowerWatch 2 is seeking investment by Indiegogo and can be pre-ordered at $ 199 (about 21,000 yen). The product version will be released after June 2019, and the product version is expected to be 499 dollars (about 54,000 yen).
