A DIY e‑ink watch that outsmarts many smartwatches
A DIY e‑ink watch is a home‑built smartwatch that uses an electronic paper display and custom software, offering over 20 unique watch faces and Pebble‑style apps while running on an inexpensive development board instead of a commercial wearable platform. It is more than a quirky hobby project; it’s a blunt argument against the idea that only big brands can define what a smartwatch should be. Over on a community dedicated to e‑ink projects, maker Nav‑Tech revealed a self‑built e‑ink smartwatch that runs on the Waveshare ESP32‑S3‑ePaper‑1.54 DevBoard and borrows design cues from the classic Pebble watch to shape its apps and interface. The result is a watch that looks modest but behaves like a pocketable toolkit: timepiece, productivity aid, and reading device, all controlled by the person who built it.
Over 20 custom watch faces, built for e‑paper life
The most striking part of this DIY e‑ink watch is its gallery of custom watch faces: right now, it has over 20 different faces tailored to the quirks of e‑paper. That number alone would put some commercial wearables to shame, but the real story is how those faces tie into purpose‑built apps. According to the project description, “This DIY e‑ink watch has 20+ faces and uses Pebble‑style apps optimized for e‑paper displays.” The watch already includes an alarm, a Pomodoro timer, an e‑reader, a dice roller, a weather app, and the ability to record voice memos, with a vibration motor and offline Wikipedia support currently in the works. Instead of chasing glossy animations, the maker leaned into monochrome clarity and static layouts that play to e‑ink’s strengths, turning each face into a focused tool rather than a flashy skin.
Makers are quietly building their own smartwatch ecosystem
Nav‑Tech’s e‑ink smartwatch is not an isolated curiosity; it sits beside other maker wearable projects that treat the wrist as a programmable canvas. One example is an ESP32‑C3 Smart Watch & E‑Reader, a feature‑rich smartwatch and e‑reader built for the ESP32‑C3 Super Mini with an OLED display, which combines a digital watch with an e‑book reader and a web‑based content management system. That project shows how a modest microcontroller can handle a real‑time clock, deep sleep power saving, persistent time and reading progress, and a Wi‑Fi content manager through a responsive web interface. Together, these builds show that a maker doesn’t need a proprietary platform to create a capable wearable. Between Pebble‑inspired app design on e‑paper and OLED‑based smart watches with e‑reading features, the community is quietly assembling an ecosystem of experimental wrist computers.
The catch: openness is promised, not here yet
For all its promise, this DIY e‑ink smartwatch is not yet something you can rebuild tonight. The maker has not released the source code or blueprints, noting that, for the time being, they “hasn't given away the source code or the blueprints on how to make your own.” That limits the project’s immediate impact: it inspires, but it cannot be cloned or forked without waiting. There is a hopeful note, though. In the comments, the creator explains they are setting up a Ko‑Fi page that will provide all the files used so other people can access the source and STL models. The tension here is real: community‑driven wearables thrive on openness, so delaying file release slows the momentum. Yet even this halfway state signals an important shift—makers expect reproducible, shareable smartwatch designs, not sealed gadgets.
Why this DIY e‑ink smartwatch matters
Nav‑Tech’s DIY e‑ink watch is important because it reframes the smartwatch as something you can build, tweak, and extend yourself, instead of a sealed appliance. With 20+ custom watch faces, Pebble‑style e‑paper apps, and plans to share code and STL files, it hints at a future where the default smartwatch experience is not dictated by a vendor but by the wearer. When that Ko‑Fi release lands, others will be able to study the firmware, remix the designs, and combine ideas from neighboring projects like the ESP32‑C3 Smart Watch & E‑Reader, which already shows how deep sleep, e‑reading, and web‑based content management can coexist in a tiny device. If this is what a single hobbyist can produce, commercial smartwatch makers should pay attention: the most compelling wearable interfaces may emerge not from boardrooms, but from workbenches.
