Description

Watchy is an E-Paper 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-Paper display delivers a beautiful crisp image clearly visible under bright sunlight, and requires no power between updates. At 200x200 pixels and monochrome, the display offers a distinctive aesthetic. Watchy has both WiFi & 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 (Arduino, Micropython, ESP-IDF, Zephyr-RTOS, etc.) Wireless network 1.

  • Battery lasts over a week so far
The e-ink display takes so little energy that the battery lasts and lasts. I haven't had to charge it since I got it and it's still going strong. I had trouble connecting it to WiFi so I haven't tried to do any face changes or anything but it's pretty cool just with the default face right out of the box. ... show more

  • Very Brief Fun Idea.
It was fun while it lasted. Was using it as is while I was looking around for a better encasement idea. Went to grab something of the top shelf in my closet (it wasn't even a really cardboard box) it slipped and hit my wrist on the way down, looked at the watch and boom. I'm not going to fault the company for it as I probably should have waited till I had a better case for it but seeing as how it can't take a small hit from a cardboard box the size of a softball, I think I will pass on getting this watch again. Price is fine just don't wear it until you have something much better to protect it. ... show more
