Watchy is an E-Ink watch with open source hardware and software. It has a barebones design utilizing the PCB as the watch body, allowing it to be worn as-is, or further customized with different 3D printed cases and watch straps. It is a unique timepiece that is also a wearable development platform, allowing users to create their own experience.

Watchy’s E-Ink display delivers an always-on, beautiful, crisp image clearly visible under bright sunlight, and requires no power between updates. At 200 x 200 pixels and monochrome, the display offers a distinctive aesthetic.
Watchy has both Wi-Fi and Bluetooth LE connectivity, allowing it to connect with internet APIs (e.g., weather, news, traffic, maps, Spotify, etc.), as well as Bluetooth LE enabled devices.
With makers/hackers/tinkerers in mind, we chose the ESP32 for its large community and support for a wide variety of development options, such as Arduino, Micropython, ESP-IDF, and Zephyr-RTOS.
The funding from this Crowd Supply campaign helped address one of the most frequently requested features of Watchy — an enclosure! Though we think the plain PCB look is one of the most distinctive features of Watchy, and will continue to offer new 3D printed watch case designs, we think a lot of fans will appreciate the new injection-molded plastic and CNC anodized aluminum cases.
Every Watchy Kit + Case is bundled with an injection-molded watch case!
Watchy 3D printed case - this campaign introduces a new injection-molded case in a color to be determined
For those who don’t mind the extra weight and want a more rugged enclosure, a CNC anodized aluminum watch case is available separately.
The Watchy Kit + Case includes the kit pictured below, plus the injection-molded plastic enclosure (not shown).
The Anodized Aluminum Case includes only the new aluminum enclosure — you will need a Watchy to put into it. Purchasing both the Watchy Kit + Case and the Anodized Aluminum Case offers the most flexibility.
Check out our watch face gallery. We regularly create new watch faces and showcase community creations. Every watch face is fully open source and part of our Arduino Library.
