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.

This Crowd Supply campaign addresses 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 would appreciate a nice injection-molded plastic or CNC anodized aluminum case.
Every Watchy produced as part of this campaign will be bundled with a new watch case! We will be offering three of our own designs, and we will solicit third-party submissions for a vote during the campaign. We will then select which design will be mass produced and offered to everyone!
Watchy 3D printed case – this campaign introduces a new injection-molded case in a color to be determined
CNC Anodized Aluminum Case
For those who don’t mind the extra weight and want a more rugged enclosure, a separate pledge level is available for a CNC anodized aluminum watch case. The design and color of choice will also be be decided by popular vote.

What’s in the box?
Backers of the Watchy Kit + Case (both early bird and regular) will get the kit pictured below, plus the new injection-molded plastic enclosure (not shown).
The Anodized Aluminum Case pledge level on its own includes only the new aluminum enclosure.
