Watchy is looking for investment in the crowdfunding service 'CrowdSupply'. At the time of writing the article, we succeeded in raising $ 112,239 (about 12 million yen), which greatly exceeds the target amount of $ 25,000 (about 2.67 million yen), and it has been decided to commercialize it.

The investment plan is as follows. We also support shipping to Japan, but shipping charges will be incurred in addition to the investment amount.

$ 55 (approx. 5900 yen): Watchy and plastic case set
$ 40 (approx. 4300 yen): Watchy anodized aluminum case (case separately)

Watchy is open source and the blueprints and source code are available on the official GitHub repository.
